CB650 crankshaft numbers

Postby Shoestring-uk » Sat Aug 06, 2016 3:32 am

Hi all :'( I need help, I recently bought a 1979 (RC03) CB650 and am in the process of a full engine rebuild. I have stripped the engine down but have a problem with the crank.
I have studded the books etc etc but I can only find one number on the crankshaft and that is a 1.
I.m either very thick or just plain stupid. The crankcase letters are fine being BCCCC.
I want to replace all the shell but am stuck without any numbers. I have the color codes from the old shells.

Regards Dave
