'02 mainshaft bearing
I gather that the gearbox mainshaft bearing on the '02 640 engine is weak...anybody out there changed theirs?
What are the symptoms of the bearing breaking up? My clutch has been noisy since I bought the bike, several thousand miles ago.
Is it possible to replace this bearing without splitting the crackcase halves, or is a full strip necessary?
In which case, any other mods worth doing to improve the '02 engine?
thanks in advance
Neil
