I've just picked up a 65 CB160 to prep for racing and upon pulling the engine apart found that there was water in the crankcase and a lot of rust including on the crankshaft counterbalancers though the shaft and bearings look clean. There's only about 2200 miles on the bike and though it looks like it spent a lot of its life outside. The main bearings don't look or feel bad but I don't trust them. Am planning on having the crank cleaned up and balanced and figured I'd replace the bearings. Only trouble is they're pretty difficult to source. Looks like the rod big end rollers and the end bearings can be had but the center ones seem to be unobtainium. Does anyone happen to have a source for them? Or happen to know their specification?
Thanks so much.
