Have you ever seen this engine assembly?. ........lm

I happened to see this photo while scrolling the Honda Shop Manual toward the section on starter motors and since I re-opened a can of worms earlier in this thread I feel obliged to watch whither they slither.

I've mistaken wires for tubes earlier, but I'm pretty sure CB72/77 carbs didn't have wires coming from the brass nipples of the float bowls--those just have to be fuel overflow tubes!

No, I haven't. The only cb72 or 77 I've seen is mine. For all I know, it may have existed only in the photo. I did see the same set-up in one of the restoration photos on Bill Silver's cd. Those are the only 2 instances.

Your asumption is correct.
It shows a prototype.
Most of the pics of the CB are of the prototype.
The bike was not issued that way.
Many changes were made.
If you look at all the pics in the HONDA manuals you will see many pics that aren't even for the bike listed on the cover.
Now ya have an idea why I don't make a book of the data I know for the reason just such as this where a pic that isn't correct comes to light and is considered fact and used to verify what the author of the massage wants to prove that my data/info can't be true.
That said I'll just sit back and watch others go crazy looking for things that never were and assemble bikes in all sort of incorrect configurations.
Good luck folks. ........lm

Please don't just sit back and watch people like me go crazy! To me, that amounts to throwing your life experience to the wind, leaving it to scatter beyond recovery. Because I have no life experience of my own with this motorcycle, I am left to draw on the experiences of others. I intend to ride my Super Hawk and I respect it as a beautiful machine that still serves its purpose after almost half a century, and that is rare these days.

I apologize if my questions/posts to this forum have shown anything other than my search for knowledge. When I began searching, I read countless posts on this forum, many of which implied that if I hadn't bought Bill Silver's cd and/or other manuals I should not expect much help with my questions. Now, after almost a year, I learn that most of the pics of the CB are of a prototype and do not depict real motorcycles that were ever sold. That is very good to know indeed.

As for the pic that came to light but isn't correct, it is a fact--that pic exists in the manual. I appreciate knowing now that it shows only a prototype. I didn't post that pic to prove that your data/info can't be true. I posted it because it appeared contrary to assertions that that configuration never existed. It's sort of like asking, "But, what about this?" when you run across something that doesn't fit the scheme of things. I'm looking for answers, not for things that never were, and I don't really want to configure my bike incorrectly--I just don't know enough about it to do that safely.

With respect to the book of data that you know: you are writing it in this forum, and I, along with countless others, will continue to appreciate it.

Shoelaces, shoelaces, shoel........ I warned you, I warned you! But that was a light back-of-the-leg slap, really.

Seriously though, every day I go out to my work -- at which I'm long-experienced and really quite good, mainly because I enjoy what I do -- I always try to consider that the day will probably teach me something, somewhere along the stream of the 36,000 seconds that I'm not at home. And I always manage to learn something every time I login here; I didn't know that the photos in the Honda manual(s) were usually of a prototype! Well, bugger me, more new info.

Always a gem from our Kerrville God.

Lucky you're in British Columbia, Wilf, which is quite a long way from Texas...........

Hi Steve,

Actually I wouldn't mind a trip to Kerrville--I would learn lots--nor do I mind a light back-of-the-leg slap if I'm learning something. It's much more palatable than dying as a result of ignorance.

Thanks for your links to Western Hills re: my starter clutch. I think I will order new rollers, springs and cups tomorrow and install them in my existing clutch outer. I'm also taking the starting motor apart to make sure everything in there can spin as freely as possible. I'm thinking that if it can't spin fast enough due to old grease or dry bearings, then the clutch might not be able to work as well as intended.

Thanks,

Wilf

Good rollers (within tolerance, that is) and springs will cause the clutch to function perfectly at the lowest of rotational speeds. Centrigoofal force takes over, once the motor is running, and forces the rollers back into their respective caves against the springs.

I just found that my starter appears to need servicing, as it occasionally doesn't spin. It's probably coming to rest across dead or dirty commutator segments; knock the motor into gear and push back an inch or so and it spins fine. I stripped and cleaned the solenoid, but it still does it.

New brushes, a good clean and check over, plus metering and undercutting of the comm are next weekend's tasks!
