Hey everyone. I just got a 03' yz 450, and i love it. But one thing, i dont think it has the power it should. From what i heard, these 03's were nuts! I just came off a 125 and expected to be very affraid of this thing, do you think it might have a flywheel weight? It hasnt been raced, it was trail ridden so i think it might. Any input would be apretiated.
