I raced a YFZ with a pipe, cam mod, K&N, and jet kit. My bike was stk with cherry bomb, baffle pulled and no lid. I beat that guy in a flat drag race 4 times in a row. No rider skill involved. He was even 20 lbs or so lighter. We would be dead even off the line and then once i got into 3rd i would pull about 1/2 a bike and stay 1/2 a bike ahead through 5th.
