pipe it, port it, reeds and geta bigger carb and take the lid off the air box that is a good start unless your on a budget then just pipe and reeds are a good start
got 600 back on my taxes just trying to figer out where to put it has stock tires rears need replaced fronts still look real good bike wasent road much run great,,,,,,,,,,,also everyone seem to say mix my fuel and do away with injector ??????????????????????????????
Yeah get a vitos oil injection removal kit (I ordered mine a week ago), its $30, and comes with decent instructions. Get some V force or Boyesen reeds, and a full Toomey B1 exhaust, you may or may not have to jet the carb, you said it was already? This is just my opinion, and what I did...but it will be a HUGE improvement
