Hey I have an 01 WR426, and its slowley gotten less powerful to the point now where it has wayy less power. Its been converted to a "YZ" all plastics, seat and tank and what not, but also the muffler, the cam timing and i beleive thats it. I rode a yz426 from the same year and it was much more powerful, the only difference between them now as far as i know, is the flywheel which apparently makes a considerable difference. Is it an easy swap? Is there anything else i need to know to make it a full conversion, and also what would be making it lose power so bad? I will appreciate any input I can get from you guys, as I am about 270lbs haha, and need all the power i can get outa this thing.

Thanks
