just bought a set of boyesen reeds for my 97 ,200 and a twin-air filter.was wandering if l have to change the main jet ? don,t know if its the original main jet, how do you tell? not sure if l have to do any other adjustments.my bike came with a pro-circuit pipe but a standard muffler.l am planning to remove the snorkel and drill a few holes on the airbox lid also.any advise will be much appreciated
