Tip: near the bottom of this long webpage, there is a

Insider tip
: with most Honda-factory-made US-issue
1971 through 1976 no-vents 750K side covers can use
either your choice of the 71-72 or the 73-76
'750 Four' upper emblems above the diamond jewels
(the newer/bigger emblem covers the indenting
used by the older emblems while most 73-76
covers still have the indenting used on the previous years);
these factory-issue no-vents covers themselves
should fit all K-model bikes models 1971-1976.

1969 to 1970, they were smooth and available in colors to
match side covers. Somewhat brittle and prone to cracking.


1971 to 1978, a stronger ribbed-surface
version was used, available only in black.


Beginning for 1973, air intake was restricted
using baffling to reduce intake roar!

Tip: the top half of the assembly is known as the air filter case;
the bottom half of the assembly known as the air filter cover.

4. "Why am I finding 3 different gas cap latches on various
US 750 K-model years throughout 1969 through 1976?"


There were 3 types: factory original, factory recall, and aftermarket.



Honda 750 gas cap latch regular        Honda 750 gas cap       Honda 750 gas cap lock
Regular thumb latch                                                      'Recall' safety latch 17550-377-315


Blame it on the recall.
These defect notices were sent out:


Honda fuel filler recall letter

TIP: any 750 Honda ignition key will open the recall safety latch.

40 years later, many dealerships still install it.
However, most 69-76 Honda 750K buyers prefer the original latch.

1977-1978 K-models placed the entire gas cap under a locking lid.
All F-models and A-models placed
the entire gas cap under a locking lid.




Least common is the aftermarket locking gas cap.

Insider tip: use the correct-color (black) mounting screws.
Use a black Sharpie marker pen to touch-up a scratch on a black screw.


Insider tip
:
on some models, left and right tank-side emblems are the same;
on some, they are different. On some models, later one of the 'side' emblems was discontinued,
causing later use of the only remaining choice to be used on both sides. Usually not noticeable.
Emblems are a soft bendable metal as to follow curves of either side of tank.

Photo above/right shows white nylon screening used on
newer model petcock. Older model uses this brass screen,
found above removable lower bowl (crud always there):

petcock screen for Honda 750 1969-1974

Note: Some earliest/first 1975 K-model gas tanks are said to have used
the 69-74 petcock and on the 'old' right side, see this blue example:

petcock on 75 Honda 750 on 'wrong' side


Insider tip: Older-style petcock has both 'short' and 'tall' versions.


Insider tip: The older-style petcock has two gas lines leaving it,
feeding the carburetors at their two inlets.
The newer style petcock has only one gas line leaving it, going to a fuel-line tee,
then the tee 'fuel joint' feeding the carburetors at their two inlets.


Insider tip: On newer style petcocks, watch for which direction the single outlet is pointing.
Some point down, some point right, some point left, etc.


Insider tip: Some early/first 1975 K model gas tanks are said to have
used the 69-74 petcock and have it on the 'old' right side.


Some US 750 K-model petcock part numbers to Google:
1969-1974, two brass outlets: 16950-300-020
1975-1976, single brass outlet: 16950-341-671
1977-1978, single brass outlet: 16950-393-015

'Tee' fuel joint: 16235-657-000

Insider tip: fuel tee 16235-657-000 is also used on some older Honda Civic and Accord cars,

so it can often be purchased in the Honda 750 fuel joint 16235-657-000  parts department of Honda car dealerships

Insider tip:
Some past owners of 69-76 530-equipped sprockets and chain have
purposely changed them 'up-size' to the bigger but less-popular 630 replacement kits.
More common though-- some past owners of 77-78 630-equipped sprockets and

  Honda 750 oil change
21. K-model oil change tips and some visual cues

You need to drain the dirty oil at 3 spots:

the oil tank, its bolt (92800-12000) and washer (94109-12000) peeking from under a plastic side cover; the oil filter housing at the front of the engine,
bolt (15420-300-020); and from the crankcase oilpan drain plug (92800-12000) and washer (94109-12000) at the bottom of the engine.

Insider tip:
The original oil filter bolt uses a small 12mm head that often gets rounded.
There is an after-market bolt that uses a larger 17mm head instead.


However, this larger bolt-head can more easily lead to overtightening,
that leading to disasterous crankcase-threads strippage.


Whichever bolt is used, use anti-seizure on its threads, and torque to proper setting.
Using the proper 12mm-head bolt with the proper wrench & torque is the correct method.


Insider note: in 1969, Honda 750s used an oil filter bolt that required
a 14mm wrench. In January 1970, Honda changed it to a bolt that used a
12mm wrench, to reduce overtightening damage. Honda Service Bulletin CB750 #13.


Many forget the correct assembly order:
The filter spring (15415-300-000) around the filter bolt (15420-300-020) goes on
the inserted filter bolt (15420-300-020) BEFORE the washer (15414-300-000) does,
with filter (15410-426-010) put on the bolt last.


Insider tip: That washer might be stuck to the old filter if you don't see it, hidden in a layer of oil.
Filter housing > then bolt > then spring > then washer > then filter > then bolt threads into engine.

Insider tip:
If you strip-out the threads of the crankcase drainplug hole at the bottom of the engine,
the crankcase itself is not damaged-- it's a headache, but you can replace the oil pan.


Insider tip:
Don't use oil that says 'Conserves Energy' or 'Resource Conserving' or 'Energy Conserving'.
Those oils are meant for a car engine that doesn't have a clutch sitting in the same oil as the engine.
They have anti-friction additives that could make the Honda's wet clutch slip.


Insider tip:
Many owners use 10-40 oil, or use 20-50 oil in hotter temperatures.


Note:
There are also 'spin on' external oil filters (like a car uses) available.

Upper portions of these bars use bar-bottom oval holes to fish switch wiring through the
bars and out the lower center bigger oval and then into the rear opening of headlight case.


Correct bars for 69-76 also have a small hole near each upper oval,
used for switch internal locator pins to lock switches from turning.


Warning: the wiring holes can slice and short wiring if any have sharp edges.

"I found 4 different chain guards supposedly for Honda 750.
Which is correct for my US
K-model?"


Black plastic: K-models 1969-1971
Watch for different lengths, hardware, metal stiffener collars under bolt/washers, collared washers, and a
metal stiffener near underside center. Possible different mounting types on the 69-71 K-models on a
year-by-year basis so be sure that separation measurements between all mounting bolt
holes on the replacement chain guard are same as those of mounts on bike.

Black metal: K-models 1977-1978

Chrome metal: none came from Honda on 69-78 K-models these years in chrome:
but they did come ONLY in chrome on 76-78 A Automatic and 75-78 F Super Sport models!

  Honda 750 centerstand changes, 1969-1978, honda750expertDotCom

30. The 3 different center stands used

Honda 750 centerstand 1969-1978
for US Honda 750 K-models 1969-1978

(followed by F-model SuperSport and A-model Hondamatic center stand listings)

These are also known as a 'main-stand' and a 'step-stand'
.


1969-1973 US K-models: 50500-300-020       
1974-1976 US K-models
: 50500-300-020B       
1977-1978 US K-models
: 50500-405-000



Improvements that occured included adding a strengthening portion, and also making a
slightly-larger (10mm) welded metal sheet ground base, both for more stability when using stand.

Many 750s with no center stand had them removed because it was
required to do so to use certain aftermarket exhaust pipes.



Note: if you are replacing a missing K-model centerstand,
there are also several special Honda 750 centerstand 1969-1978 hardware pieces you must use:

'Main stand plate' 50523-300-010 (the crescent-shaped piece)
centerstand curved plate cb750 Honda
'Main stand pipe' 50526-300-000 (the pivot pipe)
50526-300-000 centerstand pivot pipe
2.5mm cotter pin 94201-25300 (at end of the pivot pipe)
Shouldered 8x40 hex bolts 92000-080-400A (pinches mounts around the pivot pipe; needs two)
(bolts superceded by 92101-080-400A)
8mm hex nuts 94001-800-00S (need two)
(nuts superceded by 94030-08000)
Flat 8mm washers 94101-08000 (needs four)

Main spring K0-K5 50522-300-010
(spring superceded by 95014-71700)
Main spring K6 95014-71700
Main spring K7-K8 95014-71702

--and possibly a stopper for when centerstand is in the 'up' position

Spring goes from centerstand to main stand plate; main stand plate hooks to frame.

Insider tip: when the K-model centerstand is 'up' (while riding), it requires a 'stopper', usually found on the left side.
Originally it was a black rubber block on a lower left exhaust muffler.
With custom exhausts it was usually a L-shaped bent piece of metal. Without, the chain often touches the centerstand.

 Honda 750 insider secret 32

32. Insider Secret:
What the center number in a part number typically
reveals in many US Honda 750 K/F/A model part numbers

300 = generally, this part began or was modified to during 750 K-model years 1969 to 1971
323 = generally, this part began or was modified to during 500 K-model year 1973
333 = generally, this part began or was modified to during 350-Four model year 1973
341 = generally, this part began or was modified to during 750 K-model years 1972 to 1976
392 = generally, this part began or was modified to during 750 F-model years 1975 to 1976
393 = generally, this part began or was modified to during 750 A-model years 1976 to 1978
405 = generally, this part began or was modified to during 750 K-model years 1977 to 1978
410 = generally, this part began or was modified to during 750 F-model years 1977 to 1978


Example:
CB750 1973-1975 left-side mirror: 88120-333-000
This 73-75 750 mirror's 333 center number indicates that this mirror was
first designed for or used on the smaller Honda 350-F four-cylinder model.



Insider tip: 'model year' often starts many months before 'calendar year' starts.

Insider tip: In some states, on the ownership titles of many Honda 750s,
the year of first sale is often used as the bike's year,
not necessarily the same as its true model year.

33. Seat-latch types US Honda 750 K 1969-1978

They used from simple latching types at first, then seat key lock
types that matched the fork lock key and ignition switch key.


(Generally older-to-newer
pieces from left-to-right; numbered to assist with describing by phone)

1.seat latch chrome Honda 750 chrome early    2.seat latch Honda 750 1971    3.seat latch Honda 750 1971    4.honda 750 seat latch with label 72-76    5. seat latch 1972-1972 Honda 750    6.honda 750 seat latch plunger with label

Earliest models: look for different levers, catches, springs, hooks, pull directions, latches.
1971 was considered a 'transition' model, from latch style into key style.
Most seat key models match the fork lock key and ignition switch key unless past singular replacement. Often available as a matching set.
Minor continual small changes caused many year-to-year part numbers to be 'superseded by' one or more new part numbers.
Simple non-key latch models were 1969 into 1971. All 1972-1978 K-models were seat key-lock models.
Terminology: the newer-style 'spring plunger' is known to Honda as a 'seat lock bar assembly', the key portion known as 'lock assembly'.

34. The 3 brake pedal differences
US Honda 750 K-models 1969-1978

later model Honda 750 brake pedal wirg adjust ment stop, 72-76

(followed by F-model SuperSport and
A-model Hondamatic brake pedal listings)


QUESTION: "After right-side crash damage, I replaced the brake pedal with a used one.
I now find it doesn't have the horizontal piece used for the pedal adjustment/stop-screw.
Weren't all-year K brake pedals the same as my US 1974 Honda 750K?"


ANSWER: No- your replacement is lacking the tab pointing most-upward in this photo: break pedal stop on Honda 750 brake lever
(the tab points horizontally inward toward the bike when pedal is installed;
see actual tab wear-spot from adjuster stop-bolt on this photo looking down from above it).

Stop-bolt and locknut is Honda 750 brake pedal stopper seen in background.

All years had a vertical (upright when on bike) piece with a hole for the pedal return spring.
But until into the K-1 model towards K-2, there was no brake pedal adjuster or stop screw, so no horizontal tab.
Summary: there were three different types 69 through 78. 1977-1978 pedals were different in multiple ways.

 Honda 750 quick tip 35 Honda750Expert

35. Of the 16 paint color choices,
which was the most-often available paint color choice
for US Honda 750 K-models 1969-1978 when they were new?


While 11 colors were issued as a choice
in the US for one K-model year each
(Candy Blue Green 1969/70 color codes AZ and PB2C; Valley Green Metallic 1971 color code EF;
Candy Garnet Brown 1971 color code EE; Briar Brown Metallic 1972 color code LU;
Candy Buccus Olive 1973 color code LY; Maxim Brown Metallic 1973 color code QQ;
Freedom Green Metallic 1974 color code TC; Boss Maroon Metallic 1974 color code TD;
Flake Apricot Red 1975 color code UE; Planet Blue Metallic 1975 color code MV;
and Antares Red 1976 color code R-6C-S).

and 4 colors were available in the US for two K-model years each
(Candy Gold 69/70-71 color codes CQ and Y2C; Candy Ruby Red 69/70-71 color codes CM and R4C;
Excel Black 77-78 color code NH-57 or ZB; and Candy Alpha Red 77-78 color code R-9C-S or ZA),

only one color was offered as a choice for three full model years:



Flake Sunrise Orange  side cover Honda 750 flake sunrise orange  1972, 1973, and 1974.

Color code LV.

Perhaps it was popular because it had 'bigger sparkles' than all the color choices available before it.
Flake Sunrise Orange used a Candy Orange topcoat color over a FLAKE Silver basecoat;
the other 'metallic' colors instead used the 'smaller sparkle' METALLIC Silver basecoats.

flake orange gas tank Honda 750 1972 <1972   Flake Sunrise Orange  1973-1974> flake orange Honda 750 gas tank 1973 1974

In this entire 10-year K-series, only one other US-available color choice offered
when new used the bigger FLAKE basecoat under the color- 1975's Flake Apricot Red (below):


flake apricot red Honda 750 1975 gas tank

Both of these 'Flake' colors seemed extra sensitive to sun-fading damage on the tank-top.

  Honda 750 tip 36

36. Only two different swingarm grease fittings/nipple types and
locations were used on Honda 1969-1978 US 750 K-models
. . . and that helps eliminate some of the wrong
choices when buying a used K-model swingarm.


(followed by F-model SuperSport and
A-model Hondamatic swingarm listings)

swingarm grease fitting 1969-1975 grease nipple Honda 69-75 Honda 750 with label              grease nipple Honda 750 76-78 swingarm grease nipple Honda 750 1978 swingarm

Above/Left:
1969-1975 US K-model swingarms used two straight push-in 4.5 grease fittings,

one at the each end of the swingarm pivot bolt ends
(see above left, to rear of rear brake light foot switch).
Some choose to instead thread the holes and then use automotive fittings.
No grease fitting was actually on the black swingarm itself.  
A push-in grease fitting is 96201-30001
.

Above/Right:
1976-1978 US K-model swingarms used one bent-angle screw-in
grease fitting,
threaded into the bottom side center of the swingarm (see above right).
This threaded bent-angle grease fitting is 96201-80001
.


Before you change a swingarm,

usually you'll find that the old  Bushing Honda 750 swingarm 1973  brone bushings Honda 750 swingarm only needs bushings.


But sometimes you will need a swingarm.


Honda 750 swingarm 1971

However, there were 5 different K-model swingarms used
to measure & compare during those 10 years!


1969-1970 K-model swingarm: 52100-300-030B

 Honda 750 kickstand differeces 37 Honda750Expert

37. Salvage-yard and Internet searchers:
there were 4 different kickstands
used on US K-model 750s 1969-1978!

(followed by F-model SuperSport and A-model Hondamatic kickstand listings)

1969-1972 K-models: 50530-294-000
(was superseded by 50530-341-670, the 73-74 750 kickstand)  
  1973-1974 K-models: 50530-341-670 (kickstand below in red block) 
  

   kicksnd Honda 750 1973   

(Based on part numbers and supercede numbers, it appears that one kickstand,
50530-341-670, can be used by Honda 750 K-models
1969-1974).

1975-1976 K-models
: 50540-341-670 has a rubber kick-up extension     
1977-1978 K-models
: 50540-405-010 also has rubber kick-up extension (kickstand below in photo)

The 'rubber kick-up block' used 1975-1978 is the
same part-number each of those years: 50548-356-700
.

Even better, the same kickstand ('sidestand bar') 10mm x 1.25 pivot
shoulder bolt and its 10mm-thread nut can be used the entire series:

,
and its side-stand nut: 94031-10000 or 94031-110000
.



Springs: 1969 through 1978 used at least 4 different Honda 750 kickstand spring 1969-1974 K-model kickstand (sidestand) spring part numbers:

Spring K 1969-1974 is usually 95014-72400, and that spring is usually superseded by 95014-72401;
about 1975 is spring usually 95014-72401 and that is usually superseded by spring 95014-72402, and
spring K 1977-1978 is usually 95014-72402. Older numbers were also used on many other different Honda motorcycles.
Compare all lengths and designs. Used springs might be stretched a bit over years of use.




F-model Supersport kickstands:
75-78F 50540-390-000

A-model Hondamatic kickstands:
76A 50531-393-000
77-78A 50531-393-770ZA



   Insider tip: some older 750K kickstand part numbers were
also the same used on some smaller Honda motorcycles.


 Insider tip: a suspected-bent kickstand sometimes isn't bent;
the landing of the kickstand can also be affected by
1) fork tube length different from stock, 2) rear shocks different length from stock,
3) tire height different from stock, and 4) rear wheel change from stock.


Insider tip: the kickstand pivot bolt threads into 2 things--
the kickstand's threads, and into the nut.


Insider tip
: if you find a used kickstand marked Honda 750 but it has a top hole or pivot link
or it has unusual notch or hardware at its top, it likely has come from a 'Hondamatic' model--
that kickstand going down also puts the 'automatic' transmission in neutral!

 Honda 750 quick tip 38 mirror differences

38. Follow the history of the 5 main different mirror models
used on US K-model 750s 1969-1978!

(followed by F-model SuperSport and A-model Hondamatic mirror listings)

Almost any set, original or a 10mm x 1.25 -threads upstalk aftermarket, will work
for almost any 750K year (except for the first 302 K0 models, which used 11mm).
Year by year, watch for changes to length of stems
(7", 8", etc) and to diameter of round portions (4", 4 1/2", etc).
Some look like the mirror glass is glued in, others look
like a rubber lipseal is holding in the mirror glass.
Watch for frozen pivot areas.

But for collectors and restorers, here is a good general guide.


#1. The 69-70 750K 'acorn-nut clamp' model, AKA:

'the first design', or mirror Honda 750 1969 acorn 88110-300-000   mirror acorn Honda 750 1969-1970 the 'K-0 type'.

1969-1970 right-side acorn-nut clamp model, 88110-300-000
1969-1970 left-side acorn-nut clamp mirror, 88120-300-000


The smallest mirror glass diameter.
Watch for different words, logos and other by acorn nut on backside of original mirrors.
Several changes. Watch for replicas. Watch for different upstalk lengths and glass diameters.

Soon later, Honda stopped offering the 69-70 left acorn-nut mirror,
superceding (replacing it) with the 69-70 right-side mirror's part number.
This only worked because you can loosen the clamp-nut and then
flip the mirror around, making a right-side mirror also become a left side mirror!

Known as a 'transition model'.


Insider Tip:
The first 302 bikes used 11mm thread; after that, 10mm.



#2. Next came the 1971-1972 750K mirrors. No more 'acorn nuts'.

1971-1972 right-side mirror: 88110-074-000, it later superseded by 88110-329-730.
1971-1972 left-side mirror: 88120-074-000, it later superseded by 88120-329-730.

 
Insider tip:
This model mirror was used new on many other models,
including Mini-Trails and small-cc trail bikes!



#3. The 1973 through 1975 750K mirrors.
Bigger mirror glass diameter.

1973-1975 right-side mirror: 88100-333-004, it later superseded by 88110-333-611.
1973-1975 left-side mirror: 88120-333-004, it later superseded by 88120-333-610.


 Insider tip:
The 73-75's 333 center number indicates this one was
first designed for a smaller Honda (350-F) four-cylinder model.
And its 333-610 superseding number is to the 1976-1977 750 mirror!



#4. The 1976-1977 750K mirrors.

1976-1977 K-model right-side mirror:
3 part numbers, final superseding to 88100-333-611.
1976-1977 K-model left-side mirror:
3 part numbers, final superseding to 88120-333-611.



#5. End of the era: the 1978 750K mirrors.

Honda 750 mirror 1978

1978 K-model right-side mirror: 88110-333-611.

Quick Tip Honda 750 1969-1978 39 Honda 750 quick tips

39. Watch when buying used front sprockets:
there were two completely different methods used
to retain Honda US 750K
front sprockets to the shaft;
530 sprockets from 1969-1976 sprockets use one way,
630 sprockets from 1977-1978 use the other.


1969-1976 530 front sprocket type front sprocket Honda 750 1969-1976  front sprocket fixing plate Honda 750 1969-1976Honda 750

(above and below photos chosen for ease of showing sprocket-trapping comparison only, as 1969-1975
automatic chain oiler Honda 750 was used 1969-1975   chain oiler Honda 750 1969-1975
models also had some automatic chain-oiling hardware similar to this above at/in this end of shaft)


1977-1978 630 front sprocket type front sprocket Honda 750 1977-1978  8mm washer  front sprocket bolt  Honda 750 1977-1978 Honda 750


1969-1976 front sprockets were trapped on the shaft by a retainer known as a 'fixing plate' using two 6mm hex bolts.
The fixing plate matched a grove on the shaft; then slightly turned like a key; the two 6mm hex bolts into the sprocket locked it in place.
This same front sprocket retainer, 23811-292-000, was used on many other older Honda street & dirt bikes.
However, at least three different length 6mm hex bolts were used through the years, including:
some 1976 models used 12mm long, 920000-6012, superseded by 92101060120A, and some 1972 models used 12 mm or 16mm long.

1977-1978 front sprockets were trapped on the shaft by a flat washer bearing an 8mm hole
and an 8mm bolt (possible different lengths) with lock washer, the bolt threaded into the center of the end of the shaft
(possible now because past automatic chain-oiling parts stopped using these threads since 1976).
The 8mm flat washer is 90401-405-000, the 8mm X 20mm bolt used at least one year was 93402-0802000.

Both types will actually slide onto any year shaft.

changes and/or crossovers may have occurred within some shown or listed types.

Quick Tip Honda 750 1969-1978 Honda 750 muffler exhaust tip 40

41. Looking at some used stock exhaust pipes for a US Honda
750K somewhere between 1969 and 1978?
Knowing these three
Honda exhaust code numbers
will help eliminate some wrong choices.


1.Honda 750 exhaust 300 Honda 750 300 baffles          2. Honda 750 exhaust 341 Honda 750 exhaust 341 baffles        3. Honda 750 exhaust 405 Honda 750 exhaust 405 baffles 1977-1978

1. 300 series, Honda 750K 1969-1971
--Clamps on at engine--
Some of the earlier ones had
removable baffles and no 300 marking

Said to have the best chroming
Said to be less restrictive than 341 series
Said to need carb rejetting if used to replace 341s
Heat shields on upper pipes
300s are rarest and most valuable to collectors
Can use a full set of 341s instead on 69-71
but will lower value to a sharp collector

Other minor variations
A transition year

2. 341 series, Honda 750K 1972-1976
--Clamps on at engine--
Quieter than the 300 series
Reproductions available
Said to be more restrictive than 300 series
Said to need carb rejetting if used to replace 300s
Watch for clogged drain holes and rusted areas
Heat shields on upper pipes
Various baffle changes

3. 405 series, Honda 750K 1977-1978
--Clamps in at engine--
No heat shields
Reproductions available
If wanted to be used to replace 300s or 341s
(to use these later model pipes on an older bike),
see Quick Tip 92
for some of the hardware differences used to connect to engine head;
and custom mounting would be needed at muffler end.





The end-caps seen at exhaust rear are known as 'exhaust diffusers':

Honda 75o diffuser 1969-1971    diffuser Honda 750 1969-1971                        Honda 750 diffusers   Honda 750 diffuser 1972-1975

Most 1969-1971 US Honda 750K models use diffuser 18311-300-320 (above left).

1971/1972 was a transition period.
Most 1972-1975 US Honda 750K models use diffuser 18311-341-900 (above right).


If you do not require stock exhaust, there are many
4-into-2 and 4-into-1 exhaust systems available.

Quick Tip Honda 750 1969-1978 Honda 750 carburetor identification differences 1969-1978

42. Buying a used set of carburetors to replace
those on a 1969-1978 Honda 750 US K-model?
This section is not all-inclusive, but will help eliminate some wrong choices.


1. Honda 750 carburetor 1969     2. Honda 750 carb Honda 750 carbs     3. carburetor Honda 750 1978 K

Three main types:

1. 'round-top'-type carburetors that use one handlebar throttle cable into
4-separate cables to operate the carburetors (earliest, 1969/70),

2. 'round-top'-type carburetors that uses a somewhat push-pull dual-cable system using
a bar system with metal lifters to raise the carbs together (most common type, 1971/1976), and

3. new 'PD' shape, they use an accelerator pump (newest, 1977-1978).

Then there are differences within those types themselves.



Type 1:
--1969/1970
--uses a choke lever mounted at the left-most carburetor
--float bowls clamp on/tight with a large spring clip
--ID casting numbers on a flat upper horiontal area
--ID casting numbers have included 7A
--different jets sizes and needle settings used to match
exhaust pipes used and engine parts/settings used
--some earliest castings may have no number

Type 2:
--1971/1976
--uses a choke lever mounted at the left-most carburetor
--float bowls clamp on/tight with a large spring clip
--ID casting numbers on a flat upper horizontal area
--ID casting numbers include 657A (usually 1971?), 657B
(most common, usually 1972-1975?), and 086A (1976?)
--Beginning 1976, concessions to EPA (smog/pollution)
include a tiny cap to limit a previously adjustable portion
--different jets sizes and needle settings used to match
exhaust pipes used and engine changes/parts/settings used each year

Type 3:
--1977/1978 750 K-models
--uses a choke cable mounted with pull-knob near speedometer
--float bowls use screws to secure to carbs
--accelerator pump on the #2 float bowl
--ID casting numbers on a vertical flat spot above float bowl
--ID casting numbers include 41A, PD41, PD42 and PD42B
--Concessions to EPA (smog/pollution) include leanness and some previously
user-changeable portions are now no longer removable or adjustable

--needle clip in 77 carb is adjustable but not in 78 carb
--have a '77F with PD42B carbs
--PD41 carbs most often from K7 models; PD42 carbs most often from K8 models.


Compare for different linkages, return springs, and locations of gas inlets and springs.

1969-1974, the gas tank fed the carbs from right side. The petcock had two fuel lines to the carburetors.

Beginning 1975, the gas tank fed the carbs from left side.

This newer petcock had one fuel line, that went to a fuel-line tee, then two fuel lines to the carburetors.


Some castings have different number
but are the same except for original jetting.


Different float types such as brass and plastic.
Inspect them for damage or pinholes.



 Insider tip: while carbs marked 'PD43A' and 'PD44A' look like the 'Type 3' carbs listed above,
they really are only for the Hondamatic models, are smaller, and are lower-performance.


carb set

| Insider tip: Some owners of A-model Hondamatic 750s replaced
their carbs with the 77-78 K's slightly larger PD carbs,
but not necessarily for better performance!
They often do this change only
because NO factory replacement
rubber carb boots (connecting the
carbs and the engine head)
are available for Hondamatic carb sets.

VINTAGE CB750 has remanufactured these
A-model rubber boots and sells a set for about $100.

The original Hondamatic carb boots become
hardened and allow intake air leaks.

(QuickTip 53 has more info about carb boots)
Also, some A-model owners have changed over
to older round-top K-model carbs and boots.





Honda part numbers for some complete
K-model 4-carb carburetor assemblies:
K6 16100-300-671
K5 16100-300-670
K4 16100-300-034
K3 16100-300-034

Insider Tip: Honda lists the same part number for complete 4-carb
carburetor assemblies for K3 and K4 models: 16100-300-034.
Complete carb assemblies from all other years
each had its own assembly part number.

Insider Tip: part numbers for complete 4-carb carburetor
assemblies for K7-K8 models have a -405- center number.



Note: This section is not all-inclusive to carb variations. Additional minor variations, internal variations,
different part numbers, changes and/or crossovers may have occurred within some shown or listed types.

Note: front fenders use various hardware changes and rubber/plastic grommets, hose routing,
solid mount vs rubber mount, spacers and speedo cable guides. Measure and compare mount holes.
Some used isolators. Different fork leg years have different front fender mount patterns.


Note: Honda refers to the chrome mounting hoops as fender 'stays'.

Insider tip:
No US F-model SuperSport or A-model Automatic
Honda 750 used a forward hoop on its front fender.

Quick Tip Honda 750 1969-1978 48 Honda 750 insider tips

(This is a question we occasionally receive)

48. "I know that sometime in 1972, Honda made little-known restriction
changes to the bottom half of the US 750 air-filter case 'cover' (bottom half).
It made the air intake reduced, via baffling, this restriction to
supposedly to reduce the audible sound of air suction 'intake roar'.
Besides less power, my '74 750 does not have the clean 'intake sound' that my older 750s did.
So, I want to know the part number for the bottom half
of a 1971 air-filter case so I can compare and/or modify.
It would be ribbed black. Not a '69 or '70 bottom half, those are color-matched and different.
And not a '341' part-number case, that is the late '72 and newer restricted model."


Honda 750 1971 air filter bottom

Seems that the 1971 K1 part number might be 17231-300-030B.
However, many used '300' parts for sale used on the Internet are really '341' parts--
the sellers
sometimes used quick or weak research to help list their parts for sale,
sometimes using wrong part numbers.



Here is a general list of K-model air filter housing bottoms: (known as 'covers')
K0 1969-1970 year models, housing is often the same color as gas tank and side covers,
through frame #10444649 which is the last K0 frame: 17231-300-020-(color code here).
K1 1971 year model, black only, beginning with frame 1044650 which is the first K1 frame: 17231-300-030B.
K2-K6 1972-1976 year models, black only: 17231-341-010.
K7-K8 1977-1978 year models, black only: 17231-392-000.


 Insider tip: the baffling in your own air-filter case bottom can be modified.
Baffling can be removed (back to old intake roar)
or have holes drilled in baffling (a little more intake roar).
Sound is more noticeable on bikes with fairings or windshields, or when opening the throttle wide.

Insider tip: drilling at the wrong place will allow water in.

Quick Tip Honda 750 1969-1978Honda 750 gas tank trim 

49. There was chrome plastic trim/molding along the bottom edge
of the gas tank
of every 750 K-model 1969-1978.
They are NOT all the same. Below are the three main differences.


1969-1970: chrome plastic trim, all silver chrome (no stripe)
gas tank trim molding Honda 750 1969-1970
gas tank trim gold Honda 750 1969-1970

Uses clips 17544-323-000 and 17545-323-010.



Usually, original and reproduction tank trim are both available.

A-model 750 Automatics also used bottom-edge chrome trim on their gas tanks.
But F-model 750 SuperSports did NOT use bottom-edge chrome trim on their gas tanks.

Quick Tip Honda 750 1969-1978 Honda 750 exhaust heat shield differences

50. There is one muffler heat shield that fits all US Honda 750
K-models 1969-1976 (1977-1978 used no heat shields):


Honda 750 exhaust heat shield 1975 blue Honda 750 1976 red heat shield

18315-300-020 Honda 750 exhaust heat shields

Insider tip: Honda used these polished-with-black heat shields above starting
with
frame #1044650 in September 1970, which was the first US 1971 K1 Honda 750.
But for the earlier 1969/1970 K0 US 750 models,
up to frame #1044649 (the final 1970 US K0 750),
the heatshield used was 18315-300-010: a dull silver finish with black (see examples below):

Honda 750 exhaust heat shield sandcast 1969   Honda 750 heatshield sandcast
This dull 69/70 part was superseded by the 71-76 polished part 18315-300-020.

Note: Honda refers to all US 750 K-model heat shields as 'muffler protectors'.

Quick Tip Honda 750 1969-1978 Honda 750 uses 5.5 ID fuel line
(This is a question we often receive)

Honda 750 fuel line bad
 fuel line Honda 750
51. "I bought an old US 750K and the
rubber fuel lines from the petcock to the carbs
are destroyed.
My local auto parts store had hose sizes and
clips that didn't feel right. What do I need?"


Using the wrong parts looks bad and can cause trouble. All correct parts are available.

There have been two sizes of fuel line during 1969-1978 US K-models.


SIZE 1, original small fuel line, 5mm, all 69-70 K0 models,
and also for about the first third of the K1 1971 year-model:


The 1969/1970 'K-0" model, and also about a third into the
K1 1971 year model production, used a smaller 5mm size fuel line,
used until frame #1071335 (which was about 1/3 through the K1 model year).
Examples of this smaller fuel line are 95001-50160 and 95001-50280.
A smaller (5mm) retaining clip was used,
'Fuel Tube Clip 5mm' #95002-250000.

Explanation: There were about 77,000 750 K-1 models made.
The first K1 (1971 year model) was frame #1044650.
The smaller 5mm fuel line was continued to be used through
frame #1071335, which means it was used on the first almost 27,000 K1s.
The following next almost 50,000 K1s used the bigger 5.5 fuel line and clips instead--
but the same petcock was used both before and after the change.



SIZE 2, improved larger fuel line,
used for the last two-thirds of the 71 K1 year-models through to the end of 1978 model:


Fuel line: Not the SAE similar-sizes at the auto parts store.
Correct Honda 750 fuel line from gas tank is 5.5 ID   Honda 750 gas line 5.5mm 95001-5500160M
For US Honda 750 models since frame 1071336
(one-third through the K1-model year),
used the 5.5mm ID 95001-5500160M black fuel line,
fresh and pliable, available online and at Honda
dealerships in bulk or by the foot or in pieces.

5.5mm is correct for the 750's brass ports and for the factory clips.
--Not 'clear' fuel line that will quickly harden and split.
--Not wrong size fuel line that might
leak, split, slip off, or collapse at a bend.

--Not 'vacuum' line that isn't fuel-resistant.
--Not hose unrated for heat.



Clips: All 71-78 US K-models since 1971 frame 1071336 (one-third through
the K-1 model year) use clip #9500202100 at the hose piece ends.

Honda 750 petcock clips  Honda 750 fuel line clamps  Honda 750 hose clip
Known as 'Tube Clip B10".
They work with the catch-rises on the petcock and
with the catch-rises on the other connection points.

Get a few extra clips as they are easy to lose during installation.
Don't use Honda motorcycle fuel line hose clamps!


Tee: 1975 and 1976 US 750 Ks use an under-tank fuel-line 'tee' splitter
in between their single-hose petcock and the two carburetor feeds.
Honda 750 fuel joint 16235-657-000
Honda calls this tee a 'fuel joint': its part number is 16235-657-000.
Be sure to replace all 3 hoses connected to this tee.

This tee was also used on some older Honda cars.


Insider tip:
Slit the end inch of old hardened hose Honda motorcycle fuel line
Honda 750 petcock brass press-in portat the petcock end before pulling the hose off.
Otherwise you might accidentally pull out a pressed-in brass port from the petcock body.

Quick Tip Honda 750 1969-1978 Honda 750 handlebar clamps idiot lights

52. From 1972 through 1976, US Honda 750
K-models used handlebar-clamp assemblies

that had built-in indicator lights
in their center.
There were 3 different versions:

Quick Tip Honda 750 1969-1978 Honda 750 carburetor intake insulation boots

53. Often a cause of poor performance is intake air leaks. Now no longer sealing 'air-tight',
leaking are the old cracked & hardened carburetor 'insulator' rubber boots which
originally were also meant to keep carburetors cool and reduce vibrations from the engine.
Equivalent to an intake manifold on a car, but rubber instead of metal, and four instead of one.

For US K-models 1969-1978, there have been 3 versions of the rubber carburetor insulators.

1969-1970 year K-models (K0)
Insulator A, needs two: 16211-300-305
Insulator B, needs two: 16212-300-305
Metal insulator band: 17255-300-000
Insulator band's 4X22 cross-screw: 93500-040220A
Used these parts above through engine #1044805,
which was the last K0 1970 model year engine.


1971-1976 year K-models (K1-K6)
Insulator A, needs two: 16211-300-030

Insider Tip: don't use hoseclamps. Use the correct bands.





For US Super Sport F-models 1975-1978,
there have been 2 versions of the rubber carburetor insulators.

1975-1976 Super Sport:
Insulator A- 16211-300-030 (same as K-model of same years)
Insulator B- 16212-300-030
(same as K-model of same years)
1977-1978 Super Sport:
77-78 Honda 750F Super Sport carb insulators
Insulator 1- 16211-410-000
Insulator 2- 16212-410-000
Insulator 3- 16213-410-000
Insulator 4- 16214-410-000





For US Hondamatic A-models 1976-1978,
there have been 2 versions of the rubber carburetor insulators.


1976 Hondamatic:
Insulator A- 16211-393-000, uses two.
Insulator B- 16212-393-000, uses two.

1977-1978 Hondamatic:
Insulator 1- 16211-393-020
Insulator 2- 16212-393-020
Insulator 3- 16213-393-010
Insulator 4- 16214-393-010
These '393s' are the least-available of all US 750 insulators.
77-77A insulators are smaller diameter than K/F insulators due to
the A's smaller carburetors. Their curves/shapes are different too.
So, some 750 Hondamatic owners end up replacing their carbs with K-model carbs of the
same year when they can not obtain original Honda 750A carb insulators when they get too stiff/leaky.
However, VINTAGE CB750 has remanufactured these and sells a set for about $100.

Quick Tip Honda 750 1969-1978 Is my Honda 750 a sandcast?

(This is a question we occasionally receive)

54. "I have a K-0 model Honda 750.
I believe that makes it a valuable 'sandcast' engine model.
How can I verify this?"


'Sandcast'-molded engine cases have a rough surface, like sandpaper.
Used only for the first 7414 Honda 750 engines made,
then a stronger (and smoother) casting system replaced it.

Not all K-0 Honda 750s had engines that used the 'sandcast' engine cases.
Easiest way to verify is with your engine number.
Sandcast engine cases were #1000001 through #1007414.
The last 750 engine that used sandcast cases was #1007414.
If numerically yours is higher than 1007414, then not sandcast.


Original sandcast engines used Honda 750 sandcast oil filter housing case Honda 750 sandcast oil filter case this smooth oil filter case,
but many were later replaced with the newer 'finned' oil filter case.

Quick Tip Honda 750 1969-1978 Honda 750 oil lines 1969-1978

57. Keep just five threaded oil tank lines in stock,
and you can replace any one used on any US Honda 750 K-models 1969-1978!

Honda 750 oil tank with hosesoil tank hone Honda 750

The oil tanks on these Honda 750 K-models all have two oil lines thread-connectored to the bottom of the oil tank.

Honda calls the hose with an angled threaded metal fitting at the tank end 'Oil Hose A'.
It threads on to the back half of the oil tank.
The hose with a straight-on threaded metal fitting (see photo above at right) at the tank end is 'Oil Hose B'.
It threads on to the front half of the oil tank, next to the tank drain bolt.
Both hoses have angled bolt-on fittings at their engine ends.

Hose A>oil hose A Honda 750               Hose B> Oil hose B Honda 750

1969-1972 Hose A: part number 15510-300-007
1969-1972 Hose B: part number 15520-300-007
1973-1978 Hose A: part number 15510-300-017
1973-1976 Hose B: part number 15520-300-007
1977-1978 Hose B: part number 15520-392-020



Some early-model hoses were gray instead of black. Not to be confused with aftermarket hoses that used stainless-steel braiding.

On sandcast engines,
the earliest type hoses were smooth fabric, not webbed, and the metal ferrule was not crimped.
Honda 750 oil hose sandcast
The next hoses used were webbed fabric, but still used smooth metal ferrules.

Ultimately, all 750 hoses became webbed fabric with crimped metal ferrules.

Quick Tip Honda 750 1969-1978 Honda 750 front brake disk rotor differences

58. After a few early front disk brake rotor improvements,
US Honda 750 K-models used 3 different part numbers for the factory rotors.

(Part numbers below for A-model and F-model rotors too!)

3.  1976-1978 K-models   disk brake rotor 45120-392-000


Note: K-model disk rotors were 295mm.

Some disk-to-hub hardware differences:
All K-model disks used 6 nuts and bolts. But 1969 through 1975 also used 3 flat lockstrips called 'tongued washers' that connected across
two bolts each; each flat strip had 'fingers' that were bent up to prevent the 8mm hex nuts 94001-080000S from vibrating loose/off.
Honda 750 front brake tongued washers 90522-300-010   tongued washers Honda 750 front wheel
The tongued washer (lockstrips) used were 90522-300-010 from 1969-1973, later superseded to 94108-18000.
1974-1975 K-models used tongued washer (lockstrips) 94108-18000.

1976 through 1978 K-models did not use the flat lockstrips; instead they used 8mm 'flanged' nuts 90309-357-000 for vibration security.

Quick Tip Honda 750 1969-1978 Honda 750 master cylinder differences

61. Salvage-yard and Internet searchers:
there were several variations of front brake master cylinders

used on US K-model 750s 1969-1978!


Honda 750 master cylinder sandcast  Honda 750 master cylinder  

Bring your old master cylinder, and compare for different: colors, caps, cap styles, levers, mirror mount heights,
switches, adjustment hardware, labeling, lever coating, fill-line inside, brake line connection end lengths, and more.
Some part numbers are shared below in case you would also like to research by Google.



Master cylinder assembly part numbers

K0 45500-300-030, had an adjustable lever stop (later superseded by 45500-341-771).
K1 had two variations:
--K1 early, from frame 1044650 to frame 1071335, was 45500-300-040
(later superseded by 45500-341-771)
--K1 later, almost halfway through the K1 year model, from frame 1071336,
was 45500-300-050 (later superseded by 45500-341-771).
K2 45500-341-671.
K3 through K6: 45500-341-771.
K7 45500-405-671.
K8 45500-393-771, has brake light switch 35340-393-771 on it


This part number was either the original or the replacementHonda 750 master cylinder 45500-341-771 master cylinder for K0 through K6 750 models.



This 45513 part number was either the Honda 750 master cylinder cap 45513-341-771 original or replacement master cylinder cap for K2 through K8 750 models.
KO bikes and some K1 bikes originally used silver concave cap 45513-300-020 > Honda 750 silver master cylinder cap  
Honda 750 black master cylinder cap < Starting within K1 and continuing through K8 models, various black flat-top variants > Honda 750 master cylinder cap 45513-341-771

.



The mystery of the adjustable front brake lever stop
that disappeared from US K-models after only one year!

For only one full US model year, K0, Honda used an adjustable lever stop for the front brake lever.
It was made up of the three little parts below-- 1) lever adjustment bolt 45518-300-003;
2) tanged washer 45525-300-000; and 3) 8mm hex nut 94002-080-000S:

1>Honda K0 750 master cylinder lever adjustment bolt      2> tanged washer Honda 750 K0 master cylinder      3> K0 Honda 750 master cylinder hex nut
But beginning with frame #1044650 (the first K1 750),
the lever stop was never again a listed part of the master cylinder for US K-model 750s.
Instead, the hole used was capped off with three different parts involved in photo below, for models K1 through K6:

A) right handle bush stop (a short rubber tube, shown below already installed in master cylinder) 45526-300-000,
| superceded by 45526-341-000; B) lever bush plate (sheet metal with a locator nub and a bolt hole) 45527-300-000;
and C) thin 6mm nut 94002-06000, superceded by 94002-06000S.

Insider Tip: Some K7/K8 cylinder heads have a '392' casting mark.

Insider Tip: Some 77/78F cylinder heads have a '410' casting mark.



Do you have an oil leak or seepage ABOVE the head?
Usually, this is the one-piece 'valve cover gasket' aka 'cylinder head cover gasket' .

Good news-- many don't know that it can be changed with the engine in the frame!
There is a YouTube video that shows the steps.
Be careful-- it is easy to put the gasket on backwards.

68. Is your gas tank no longer firmly secured while being cushioned?

All US Honda 750 models used gas tank rubber mounts at both ends of the fuel tank.
40 year old rubber mounts harden, tear, shrink, stiffen, disintegrate and/or fall out.

Honda used these same rubber front cushion mounts
for all model years-- and for all models K, F, and A:

Quick Tip Honda 750 1969-1978 Honda 750 fork boots gaitors 1969-1976 51611-300-000

69. Fork boots aka fork gaiters or accordion boots:
US Honda 750 K-models 1969-1976 all used the same boots!

Honda 750 fork boots 51611-300-000 same 1969 through 1976
  fork boots Honda 750 K-models

51611-300-000

They protect the fork tubes from getting nicked up by road debris, which then would damage fork seals.

They fade, deteriorate, split and tear.

Must remove fork tubes away from top bridge and steering stem to install the boots.

One end of the boot connects at bottom of the headlight mounts,
the other end connects at the top of the fork legs.

Quick Tip Honda 750 1969-1978 Honda 750 battery cable

84.
Of the several positive battery cable variations
used throughout the 1969-1978 US
Honda 750 K-model
series, which one can usually be used on any model?



Honda 750 battry cable 32401-300-010
32401-300-010, the oldest cable.

Look at 32401-300-010 as 3 attached wires:
--the thick main cable,
and
--
extra lead A (round bullet connector at top in photo)
,
and
--extra lead B (flat spade connector at left in photo).


All models use the thick main cable portion.

K0-K2 also uses extra lead A and also uses extra lead B.

K3-K6 also uses extra lead A.
It does not use extra lead B.
Fold extra lead B to make it shorter,
then cover folded lead B with electrical tape to prevent its inproper use.
This was first discussed with Honda Service Bulletin #43 in 1975.

K7-K8 does not use either extra lead.
Fold both extra leads to make them shorter,
then cover the folded leads with electrical tape to prevent their improper use.



But for correct restoration standards, here are the original positive cable part numbers.
K0-K4: 32401-300-010 (has both extra leads attached)
K5, up to frame 2503719: 32401-300-010 (has both extra leads attached)
K5, after frame 2503719: 32401-341-000 (has only extra lead A attached)
K6: 32401-341-000 (has only extra lead A attached)
K7-K8: 32401-392-000 (has no extra leads attached)

become 'invisible', mechanics swearing a bike had none.
Actually, they just become so smashed flat and lose their color that they blend in with the head.
A dental-type pick often helps to find them and to remove them.

My 1973 750 doesn't have it."


Honda 750 case protector 11353-300-010

Like a mini-chainguard, it is a 'case protector'.


Part number 11353-300-010, it was used due to chains breaking and then damaging cases.
First K0 engine was 1000001. This part came on K0 engines
from 1026144 through 1044805 (the last K0 engine, mid-1970).
Some 750 owners are said to have added this to later models.

Do you have an oil leak or seepage ABOVE the head (below this cover)?
Usually, this is the one-piece 'valve cover gasket' aka 'cylinder head cover gasket'.

Good news-- many don't know that it can be changed with the engine in the frame!
There is a YouTube video that shows the steps.
Be careful-- it is easy to put the gasket on backwards.

Quick Tip Honda 750 1969-1978  Honda 750 with Harley 16" rear rim

(This is a question we often receive)
109. "I see old Honda 750 K-models listed for
sale that tell of having Harley rear wheels.
What model Harley were these wheels
taken from, and what is the benefit?"


   Honda 750 with lowering blocks and Harley rear rim  Honda CB750 with Harley rear rim  16" Harley rim on a Honda 750 hub

They aren't really actual wheels taken from Harleys!

First, the 40 spokes of the 1969-1976 Honda 750's 18" rear wheel are cut.
Then a wide 16" chrome rim is laced to the 750's hub using
shorter spokes (often from Buchanan's in Azusa California).
This lowers the rear end and the seat height, allowing for being
flat-footed at stoplights for many who used to be on their toes.

Note: for 1977-1978 K-models, Honda used a
shorter & wider 17" rim for the rear wheel.
This is a little shorter than the earlier models' 18",
and it is a little taller than the 16" 'Harley' conversion.
.


Insider Tip: changing to this type of wheel/tire usually causes higher
engine RPM on the highway. This can be offset some by a sprocket change.

Insider Tip: changing to this type of wheel/tire sometimes
prevents the kickstand from working properly.
Some owners report success in changing to the
slightly-shorter kickstand from a smaller model
Honda twin of the same era, such as a CB-350.

Insider Tip: changing to this type of wheel/tire usually
makes it harder to get the bike up on to its centerstand.

Note: Involves transition models. Additional minor variations, changes and/or crossovers may have occurred within some shown or listed types.

TIRE SURVEY:
Because many ask me
"Tire sizes are different now-- which should I use nowadays?",
I asked many CB750 riders. Here is a summary of their answers.


69-76 K models:
By far most common>Rear- 110/90-18 (like a 4.00X18).
Rear: 120/90-18
(like a 4.50 X 18, feels good on straight
but less good than a 110 on turns).
Rear- 130/90X18
(like a 5.10X18,

very wide, barely fits, poor on turns).
Front- 100/90-19

77-78K models:
Rear: 120/90X17 or 130/90X17
Front: 100/90X19 or 110/90X19

Quick Tip Honda 750 1969-1978  Honda 750 cam 1969-1978 camshafts

121.
Camshafts, for all US Honda 750 models K, F, and A!

cam Honda 750 14101-300-020

Honda lists only 2 K-model cam part numbers:
For K0-K6 it is 14100-300-020, and for K7-K8 it is 14101-392-000

This does not mean that all cams 1969 through 1976 were the same.
They weren't. There were many changes.

As with some many other Honda parts,
whenever a cam was slightly changed for a next year model,
it used the same part number of the old part and it then completely replaced the older part.
The newest part is said to be 'backward-compatible' with all years.
And the newest part will work, but possibly causing different characteristics.

So, if you want a duplicate of your original K-model's cam original lift and duration
(exact valve open and close time), you may have to seek a verified-year
used part and/or bring lobe-measuring tools such as calipers.

For 75-76F it is 14100-392-000, and for 77-78F it is 14101-410-000.


Note that according to Honda part numbers,
the K7 and K8 models use the cam from the 75-76 F model!


Different markings are observed on various used Honda 750 camshafts,
including 'R' numbers near the sprocket area.



Honda lists just one A-model Hondamatic cam part number as available:
For 76-78A it is 14101-393-000.

1969-1978 Honda 750 models K, F and A

Honda 750 spark advancer front view  Honda 750 spark advancer rear view

Found under the points/condensors plate.

Honda lists only 2 K and F model spark advancer part numbers:
For 1969-1978 K&F it is 30220-300-005, and alternate/supercede is 30220-300-154.

This does not mean that all K&F spark advancers 1969 through 1978 were the same.
They weren't. There were many differences through the model years.

As with some many other Honda parts,
whenever a spark advancer was slightly changed for a next year model,
it used the same part number of the old part and it then completely replaced the older part.
The newest part is said to be 'backward-compatible' with all years.
And the newest part will work, but possibly causing different characteristics.

So, if you want a duplicate of your original K or F model's spark advancer configuration
(exact springs, exact weight of the weights, exact markings,
exact strength of springs, exact degrees of advance,

exact time when the full advance occurs, exact advance-stopping nubs, etc),
you may have to seek a verified-year used part and/or
use close inspection with measurements.

Used for 750 K-models K3 through K8,
750 F-models 1975-1976, and A-models 1976-1978.



Insider Tip:

Do you know why the dual-front-disk 1977-1978 Honda 750F SuperSport
models didn't
use front disk rotor splash guards, yet every other 1973-1978
Honda 750 model did?
Honda 750 constar whel
Because, only for these models, Honda mounted the brake calipers behind the fork legs.


Insider Tip: K0 to K2 models did not have a disk rotor splash guard;
it was added for the K3 model as an improvement.


Insider Tip: Sometimes we find a black plastic splash guard in a parts box marked Honda 750 that is not correct.
It usually turns out to be a 43140-410-000, which is for the rear wheel brake disk on some SuperSport F models.

"Any tips for finding used luggage racks
for US 1969-1978 Honda 750 K models?"


Honda 750 luggage rack with back rest   Honda cb750 luggage rack   luggage rack Honda 750 1973


Honda did not produce a 'stock' or factory-available rack during that period.
But there were many aftermarket racks available, from companies such
as Amco,
Arthur Fulmer, Bates, Buco, Rack Factory and others.
Most current rack manufacturers were not yet established in the 1970s.

Most were chromed steel of square tubing or round tubing;
some such as Rack Factory were polished aluminum.

The main body/platform was solidly above the taillight.
Some platforms were dressed with wood, rubber or plastic inserts.

Arthur Fulmer Honda 750 luggage rack

Some also had sissy bars or padded backrests.
Backrests were either fixed for a passenger's use or
were adjustable to slide farther forward towards the rider.

Some were a one-piece rack.
Some racks used sides that bolted to the body/platform.

1978 Honda 750 luggage rack  luggage rack Honda 750 arthur fulmer

Exact-fit models usually used a front mount that
slipped under the rear shock's top nut and washer;

their more rearward mounts were typically either brackets
that attached near the rear turn signals on the
sides or was a single bracket that used a u-bolt at
the center rear of the grab rail behind the seat.


There were also less-preferred 'universal' racks that used an assortment of
adjustable mounts that let them be used on many brands of motorcycles.


Exact-fit models were different every couple of model years.
Some manufacturers said that their 1973 through 1976 K3-K6 were the same mounting.
Some said that their 1977 and 1978 K7-K8 used the same mounting as each other.
Racks for 1979 and later do not fit earlier Honda 750s.
Many racks are listed for sale on Google and eBay.

This section was added because it is is a frequent request by visitors to Honda750Expert.com!

143.
"What were the most common vintage aftermarket
(non-stock) exhaust systems
; 4-into-1 systems, etc
that were used on US 1969-1978 Honda 750 K models?"


No Honda 750 K-model from this era came
from the factory with 4-into-1 or 4-into-2 exhaust.
All Honda 750 K-models of this era came with four separate exhaust pipes.

CB750 Kerker exhaust

The most common aftermarket exhaust systems found on 1970's 750 K-models include
(alphabetically): Dunstall, Hooker, Jardine, Jemco,
Kerker, MAC, Racecrafters, RC Engineering,
Strader, SuperTrapp, Triple A, Vance and Hines,
Winning Performance, and Yoshimura
.

Most were either chrome or black.
Some required 69-76 models to convert to the 77-78 bolt-into-head style.

Some 4 into 2s had you cut off the original mufflers and slip on the new ends.
Some 4 into 2s released exhaust straight out the back;
some were 'turnouts' releasing exhaust to the sides.

Some 4 into 1s required removal of the centerstand.
Some 4 into1s interfered with oil filter removal and/or oil draining.

The muffler on some 4 into1s used a mounting
bracket up to a rear footpeg or to a top shock nut.

Many 4 into 1s were near-copies of the Kerker above.
Some had removable/replaceable/repackable baffles.



Exhaust mounting at the head:
K0-K6 used a 'clamp-around'; K7-K8 used a 'clamp-in'.
Some 4 into1s require a change to K7-K8 style.

No Honda 750 K-model from this era came from
the factory with cast wheels or 'mag' wheels.
All Honda 750 K-models of this era came with spoke wheels.


Types found were Lester (the most popular used in the US on 750s),
followed by (alphabetically) Curtis, EBP, Hayashi,
Henry Abe, Invader, Kimtab, Morris, and Shelby-Dowd.


Some brands required a changeover to rear disk brake.

"What aftermarket (non-stock) fairings
were most often used in the 1970's on
US 1969-1978 Honda 750 K models?"



No Honda 750 K-model from this era
came from the factory with a fairing.


By far, the two most popular upright-riding chest/face protecting fairings
(not the tiny 'cafe-racing fairings' used while riding bent over),
also called touring fairings, were Wixom and Vetter Windjammer.


Wixom > Honda 750 wixom fairing           vetter faring Honda 750 < Windjammer

Wixom was fork-mounted near the handlebars.
Windjammer was frame-mounted.


Wixom had cut-outs for the 750's own headlight and front turn signals.
Windjammer had its own built-in headlight and,
with later models SS and 4, had built-in turn signals.


Wixom > wixom fairing on a SOHC Honda 750  wixom fairing Honda 750  CB750 wixom fairing < Wixom

Wixom used no electrical wiring.
Windjammer plugged into wiring inside the 750's headlight shell.


Wixom > painted wixom fairing   wixom brothers fairing for Honda 750 < Wixom

Wixom used three short mounting brackets.
Windjammer had a mount that was first secured to the 750's frame,
then the Windjammer was bolted to (sits on) that frame mount.

Different height clear windshields were available for both.
Windjammer had vents available on some windshields.
Windjammer also had optional lower portions available to protect legs.
Windjammer also had storage pockets built in.
Some
pocket covers were cloth, some were hard lockable covers.


Windjammer > Windjammer Honda 750  Honda CB750 vetter windjammer  Windjammer CB750 < Windjammer

Wixom trivia: Wixom was the Wixom brothers Dean and Stan Wixom.

Windjammer trivia: Windjammer fairings were made 1971 through 1983;
models included l, 2, 3, SS, 4 and 5.
There were smaller Vetter fairing models too.

 paint color to match CB750

"Honda doesn't sell CB750 paint.
What aftermarket (non-stock) paint

is available already to try to match the colors
used on some US 1969-1978 Honda 750 K models?"


CB750 Honda paint   Honda CB750 spray paint can

Most original internal Honda color-codes are not matchable
to numbers used by current paint manufacturers,
but there are some paint manufacturers that now have paint
ready to try to match the original Honda 750 colors for some models.


Here's the main headache to matching a Honda 'color' in one container:
Honda often got each original final color in two or three steps or 'stages'-
1. A special colored primer.
2. Then sometimes a special colored metallic or flake basecoat.
3. Finally, a special colored candy topcoat.


There are some suppliers offering what some CB750 owners have
said to be a good match to Honda's results for some colors
(some are in bulk, some are in rattle spray cans):

HondaMotorcyclePaint.com
ColorRite.com
RSbikePaint.com

 Honda CB750 engine hanger bolts

Honda CB750 SOHC parts
This section was added because it is a frequent request by visitors to Honda750Expert.com!

147.
Originally there were 3 long engine support bolts
used to hang the weight of the engine in the frame.
A previous owner instead replaced them with other
hardware to mount some brackets and guards.
What are the correct three long bolts to use?


Honda CB750 engine hanger boltsHonda 750 engine rebuild

Almost all were the same on US 750s 1969 through 1978.
They are known as Engine Hanger Bolts A, B and C.
Except for one, they were long shouldered bolts with
a hex head at one end and threads at the other end.

Hanger Bolt A is the front-most long shoulder bolt.
Hex bolt 90152-300-010, K0-K8.

Honda 750 engine hanger bolt
Uses the same 10mm hardware as Hanger Bolt C does:
10mm spring washer 94111-10000, 10mm hex nut 94030-10200.


Hanger Bolt B is the lower rear long bolt,
the thickest of the three hanger bolts, at the footpegs.

12mm Honda 750 engine hanger bolt
K0-K6: 90155-300-000, threads at both ends.
K7-K8: 90155-392-000, threads at one end.
Both use the same 12mm hardware:
12mm flat washer 94101-12000, 12mm spring
washer 94111-12000, 12mm hex nut 94030-12200
(K0-K6 uses 2 nuts each on this rod, K7-K8 uses one nut each on this bolt).


Hanger Bolt C is the upper rear long shoulder bolt.
Hex bolt 90156-300-000, K0-K8.

Honda 750 engine hanger bolt
Uses the same 10mm hardware as Hanger Bolt A does:
10mm spring washer 94111-10000, 10mm hex nut 94030-10200.



Insider Tip: most of these bolts for sale on eBay
are 'replicas', not original OEM Honda bolts.
Make sure that any bolt used is the proper grade/strength.

Insider Tip: usually installed through left side with the nuts on the right side.
