hi, i have the 04 250r, and i want to start running race fuel in it.... i live in alaska, so our pump gas is NOT the best by any means.... well, what do you all recommend? my bike is totally stock.... with the race fuel, do i need to re-jet? also, my buddy has a 2002 wr426f, and he has the free flow intake, with the fmf powerbomb header, and the fmf power core 4 pipe, and up'd his jets... would the same fuel work for him too if we split the cost? thanks for the advice in advance !!!!
