i have a 2008 polaris 600rr race replica snowmobile. i bought a set of crank shop pipes from a buddy of mine. i am wondering if anyone has a crank shop jetting recomendation. i live in fort mcmurray alberta canada and we are about 2000 feet above sea level. i have v force reeds and a set of air pods. on the top pipe there is a dent and he said it was so his hood would close without burning a hole, will this effect the pipe and if so how would i get the dent out?
