Title: Owners manual
Post by: Sgt.Pinback on January 11, 2017, 03:26:00 am
I have a 69-12 owners manual.

There are "x" marks on top of some pages but otherwise it is in good condition.

I´m not selling it but would like to trade it with an earlier version. Perfect would be 69-7 or even earlier.

Actually, I dont know what earlier version exist ?

This is because they have used a prototype model to make the photos like on the workshop manual ... The double cable reveals most certainly carburetor has rudders as on the prototype of the Tokyo Salon.
This is certainly the prototype with the long course engine subsequently abandoned for the super square engine ...

How do you detect a flat seat in that picture?
Where do you see a date on/for your owners manual?
It looks exactly like mine. Honda from mid august ´69.
Frame 1676.
Frankly speaking never looked close enough to see 2 cable throttle!
But changed over when the chance came my way to have a set.
Knew from road test in magazines then, they told original model had.
Like BMW side car racers at world championships.
I used to go round Europa to watch races in those days.

Also has a K1 tank trim, solid brake line, odd disc caliper, funny clutch cover, K1 mirror, odd side covers, odd alternator cover and other stuff. Maybe its a pre production or a very good drawing Either way, it's not a production bike
The early seats were in fact much flatter than later seats

Do all US KO owners manuals show that bike?

The German manual shows a "correct" KO (in German/Dutch spec)

I would say the passenger place is much more flatter.

Date is on the back side in the right bottom corner. See pic.

Would be interesting to know what date yours is (if it is the manual # 1676 originally came with)

Uli, you're right... the seat of manual 69.12 is a plate galette like on the model of pre-production...

all the USA pre-k1 manuals showed an interation of a late pre-production bike.  the reason i say iteration is the horn and the throttle cables seen on the early owner manuals was a two-cable setup coming off the handlebar, suggesting a push-pull type throttle setup.  other differences of the bike seen in the manual are a horn without chrome cover, very different side covers. these features are different than the actual blue-green pre-production bike CB750-2113/CB750E-2113.

the earliest print date i have seen on an USA owner's manual is 69.5

Odd, they never changed that and there are some more pics from that pre-production bike (carbs, kill switch ...) to be found.

what you see in owner's manuals may not even be photographs of actual motorcycles.  these "motorcycles" could very likely be artistic depictions, such as a sketch of a photograph.  the so called motorcycle in the USA manual appears to be an early pre-production unit, but the side cover badges are late pre-production.   i feel "pictures" such as seen in front page of owner's manual are entertaining, but not reliable to form or draw any conclusions of what a production motorcycle is supposed to look like.

The motorcycle used in these pictures is the same bike as the showed to the world in the 1968 Tokyo motor show .

Sorry, never noticed that date, but it is like Steve Swan says 69. 5.

How do you know the bikes are the same bikes ? 

or do you mean the bikes "appear" to be the same bikes ?

Congrats and thanks for info. And good for you to know.

Do you know if exactly this 69.5 manual came with your # 1676?
(Mine is # 1983 so that would be the one I have to look for)

i may be wrong or having old man memory farts, but i do seem to recall the earliest print date for owner's manual is 69.4.

like i said, i could be wrong and may be confusing owner's manual as having 69.4 date as IS the earliest printing on the parts book.

i KNOW there is 69.5 print dates on owner's manual and 69.4 on parts book.

interestingly enough, the earliest print date on a service book i KNOW of is 69.8.  The Provisional Service booklet print date is 69.6

Do you know if there are anything between 69.5 and 69.12?
Title: Re: Owners manual
Post by: Steve Swan on January 13, 2017, 11:38:56 am
yes, there is, but i don't know every print date.  i KNOW there are 69.6, 69.7, 69.8 print dates on owner's manuals.

Here are several photos of some manuals  The manual dated 70.6 uses the same photo of both sides of the bike as is in the manual 69.6. It seems to be a very good artist's sketch
I do have a few others but not readily to hand so maybe the missing dates as I thought I had all 69 Manuals. My belief is May is the earliest print date.

Mr Hahn is on the money. That is indeed an early pre production bike depicted in the owners manual. The reason for the push/pull cable is the bike has Mikuni carbs fitted. Did the early pre-production bikes have Mikuni carbs fitted  ??? cos they are Mikuni carbs

the "problem" with that early pp bike is the side cover badges, correct me if i am wrong. the bike you are referring to has badges like late pp and the rest of prod.bikes.

True but those badges are not very close to production looking and a swap/drawing would be easy enough to substitute for the purpose. I don't have a good enough photo of any PP bikes but the photo posted by Gerard of an early pre production bike convinces me of the origins of the owners manual depiction. The horn, the disc, the top brake line, alternator cover, tank trim, mirror and the Mikuni carbs all point to the early PP bike. There my thoughts

Sure that book came with my CB750.
Have owned both since August ´69.
Got a shop manual too, but it is indeed dated 70.1!
For curiosity I just looked through it.
Page 136 shows a single cable twist grip.
Next page shows a double cable twist grip!
Which is not known to have been on a production CB750.
Page 156 might show but one cable, but a different kill switch.
