I have a 99 400 ex with a uni filter, and an e series slip on nd a 155 main jet. I have a sligh hesitation at just above idle speed when im just luggin along in a higher gear it sputters and it will eventually stall if no fully warmed up ,when warmed it will still hesitate but it wont stall. Also when i use engine braking there is a stream of pops and backfires,which arent bad but they are there. Is this the pilot jet or fuel screw?
