hey all,
i'm hoping that somebody here might be able to tell me what the problem is and how to fix it: when idling or going at low speeds my 4 stroke 110cc bike sounds fine, but at high revs there is this rattling sound coming from the engine or somewhere near it. a guy at the track said it could be a loose countershaft?? i know it is not anything to do with the front/rear sprockets or chain or wheels or suspension or anything like that coz when im sitting still in neutral revving it, it still has the same problem... and for some reason, at peak revs (9,500 - 12,200rpm) there is no rattling??? does anybody know whats wrong? and/or how to fix it?
cheers,
matt
