So I just picked up a 2002 yz426, I got a really good deal on it but I'm having some issues with it as it goes for trail riding. For example ... It's like a God damn wild animal and just wants to go all the time!.. I've been reading about ppl getting a higher tooth sprocket for more torque and since my problem is too much of it I was wondering how low I should go ? Currently I have a 52t rear and I think a 14 front not sure about that one though ... I would prefer to only replace one to keep things on the cheap.
