back in the day when i had my other blaster, it was stock with fmf pipe/silencer, and jetted, i wanted to race. so i went to my local track and asked about things and they said that if i put a pipe and rejet my blaster than i cand run with 200cc class anymore. so i never raced cause i wasnt good at riding back then. now days i would race if i had time, but now i dont have time
