Just wondering if anyone would have an idea what my jetting should be.Have a k&n air filter with a K&n jet kit. Also has an FMF powercore 4 pipe. Currently has a 142 jet. Most riding is done at 5000 to 9000 feet. I did not put all this on the bike. Bought as is so information is hard to come by as i dont have all the paperwork from product purchases.

 

i would put in a dynojet 146 or the next size larger in the kit (i don't know what that is). leave your needle clip alone and turn the fuel screw 3 turns out from lightly seated. good luck
