ok fellas here's the skinny, My bro has an '11 CRF450 with the Yoshimura stage 2 engine, stage 2head and cam. now the problem is that it start's like a frig'n dumptruck, bike runs great, but just doesn't wanna start. We/they have richend (sp?) it up from the bottom up to about 2000rpm and that helped a little but not much and Yosh has been NO help what so ever, just well it works fine with our bikes
so anybody have a clue of what to attempt/adjust so we can start it easier??
