you're gonna want to get online and just order a jet kit, its the simplist thing to do really, its worth the extra dollars. if you repipe it you're going to want to jet it anyway especially if you are modding the airbox. let it get some fuel. if it were me, i would just buy a bigger main jet and bump it up from a 145 main to a 150 or a 155 main, and then adjust the air screws to make it work, but a jet kit is probably your best option.
