Is there any way to tell what year the engine is by looking at the # on it. Grayracer says its a 2nd gen engine and its suppossed to be a 5 speed. He seems to know what hes talkin about. Ive heard that mx riders often take out gears. Could that be it. The guy that sold it to me told me it was a four speed. Now im startin to get pissed. I feel like takin it back to him and burnin rubber on his face in all FOUR gears. And if its supposed to be a 5 gear ill just have to owe him one.
