put a 170 main 2 sizes bigger in the pilot and find a couple tiny washers to raise the needle the distace of a couple positions since the needle isnt adjustable. cut the airbox top(a monkey can do it) and get a new hi flow exhaust and header(gotta ahve the header) expect to pay 7-800 bucks. The washers i am talkin about are tiny very tiny but it beats buying a new needle. mine is done that way and works fine i have NO trouble whatsoever and i ride windrock and blackmountain. The main thing is go to 170 and two sizes on the pilot which will help with the bikes cold nature.
