Recently installed a full GYTR exhaust and jet kit on my 03 raptor.Followed directions with airbox lid on. It runs great but the plug gets black real quick.
Seems rich @ idle. Should I go in with the pilot air screw or down on the jets or am I missing something else.Any help greatly appreciated.

Try removing the lid and see what happens

i had the same problem....... try to use the stock jets or you can use smaller jets like 142 and 147.5........
good luck
