Just how many people out there are having the oil squirter problem? I know of several people who have the 04-05 models that haven't had any trouble with their motors.

it kinda depends on how hard you ride it. some have trouble and some don't! if you put a higher compression piston in there you raise the chances of this happening do to the added stress on the wrist pin. if you ever have to tear it down its a good idea to get this done cuz i've seen some major damage from this!
