Default Re: What's your most desirable accessory for a China Girl?

I agree 100% on the bearings and a better balanced crank assembly.

I never had one of these engines back when they had the bronze bushing for the upper bearing instead of the caged needle bearing like they do now, but it seems I have read where people had said the engines with the bushings were better balanced, if that is true it seems that maybe removing some material from the cranks counter weights opposite the rod journal might help the balance since the piston/pin area is lighter now than it was with the bushing.....Shrug?
I dont always ride WOT, but when I do..I do my best to keep the rubber side down..Ride safely my friends!
