Default Re: what did you do to your motorized bicycle today?

have you remover cover on left side of engine and made sure that the bucking bar and the 8mm ball bearing that is inside the clutch shaft have plenty of good high temp grease on them?

you might also run the engine with the right side clutch cover removed and see if you can tell if the squealing noise is coming from that area or not.

I dont always ride WOT, but when I do..I do my best to keep the rubber side down..Ride safely my friends!
