Dear All, Have had a CB77 lying around for a number of years, and am starting restoring/rebuild. It is a 1966 (alloy front fork tubes), and I have found that only one of the fork legs has the spring guide (part no 51523-268-000). How critical are they, since there do not appear to be many to be obta...

Hi G-Man, Many thanks for your replies and information. My Friend has been in contact with most of the "more recognised" CB72 (250 and 350 versions) tuner/builders, and has been given the impression that the Yamaha big end roller bearing and the 25 mm crank pin is the way to go.

G'day G-Man, Many thanks for your reply and information. Firstly the bike is not in fact a "CR" Production Racer, but a "CB" raised as close to CR spec as the could manage.

Cheers, Arthur

The Carbs on the original are Keihin PW26, but with the mixture they were PW22. Restoration on both bikes will start in a couple of months, but I will likely need...

G'day All, Been a while since I have looked at the Forum, but now is a good time! I have a 1966 CB77, just finished the engine, and wanted to start on the next Honda project. I bought a bike (well frame, wheels, most of the engine) which was supposed to be a 1963 CB77. Turns out the frame is CB77, b...
