hey guys what up. i dont feel like searching through 125 pages to find this thread. but someone is bound to know. i have a 440ex. 11:1 wiseco piston. stage 2 hotcam. outwears cover for lid. drilled and filltered holes. and twin air filter. and running a fmf jet kit. i dont remeber what size the pilot jet is but there was only 1 in the kit. my choke is removed and i have a 170 main. i still have the stock header and just got a motoworks slipon. i heard i could go up to 190? what would be a respectable jet size? thanks guys
