Alrite like u all kno I have the 85 250r tht won't hit the power band so I decided tht maybe I should just run the helll out of it and see if it does anything, holy s*** it worked!!!!!!!! And I have another question, how do I check if it has had internal motor work done like porting or stroking because I smoked my friends 450 i kno somethins been done to the inside
