i agree its a good mill, but how do u expect people to bring diff pipes to a race, lets get real majority of racers are not sponsored, and pipes are not cheap, i think i will jump one tooth, and the track i run on , has a long straight in the back, i will loose easy 2 seconds there and by the time i get to the end, i bet this motor will be peeked out, has lots of bottom end , but u do need top end at times, i will test it next week at my local track, good motor so far, just have to see how it actually runs on a track now
