I bought a old 1999 yamaha rt100l. Its a lil two stroker. This thing has been ridden quite alot since, and nothing has been done to the engine. It doesnt seem like it has lots of power left. Could it be time for a topend? What would give me the best power back?? I need more powER! :cool:

And the bike has around 120psi compression and it says it should be around 160. Whatever the hell that means :uh:
