Remove the baffle from the exhaust and the snorkel from the top of the airbox. Then rejet for the increase in air. go to your dealer and order these parts:
Pilot Jet--99103-KPT-0XX0 (XX is the jet size, stock is 40, go with a 42)
Main Jet--99113-GHB-XXX0 (XXX is the size, stock is 98 go with a 110, 112, or 115 depending on your altitude and temperature that you ride at)
Needle Jet--16012-KPT-921 (some guys, me included, didn't like the results of this needle and went back to the stock needle with the clip in the 4th position)
While you are at the dealer, pick up a Hi-Flow Air Filter such as a TwinAir.
This simple and inexpensive mod will really wake up the bike. Best bang for the buck.
