i just got a white bros. slip-on for my raptor. i've been doing some research on what jets to use/buy but not exactly sure because my bike is pretty much stock.

it's an: 01, k&n filter w/lid, no motor mods, and i live in the louisville, ky area....any suggestions?

up 5 on both sides, start fro there. most people jet too high. if you are looking for a little more umpf, remove the snorkle on the lid...the baffles inside it really restrict airfolw. Stock jets are 140 in the left carb and 145 in the right. I would go buy a 150, put it in the right, and move the 145 to the left carb. You shouldnt have to do much more, needle clip position if you are sitll running lean in the middle rpm...prob wont even have to mess with that though. You may need to play with your fuel mixture screws, turn them out 1/2 turn more than stock.
