my bike has about 35 hours on it. (approximatley) while i was riding today everything ran fine and sounded good other than the fact that it has been getting harder and harder to start. (still has good compression) but when i went to practice my starts while revving the bike out and about to release the clutch it sounded really odd almost like i was over revving it. ALOT! but i wasn't. is it about to blow? i'm ordering a new top end tommorow anyways but it wont be here until next week and i have a race saturday.
