[QUOTE="MXP1MP, post: 1014969, member: 20581"] Try going down again on the pilot the next size is 37.5 from the 40, mikuni starts going by 2.5 under 40. by 5's 40 and above. Pay more attention to the throttle position the pilot only affects first 1/4 anything beyond that to 3/4 is all the needle you ride most of the time on the needle. It's trail n error it's still fouling plugs black that tells me too rich still. 2.5 turns out on the air screw is like the very max you want for an air screw adjustment. Try getting a few size small pilots the 37.5 the 35 and try those if it still fouls it's time to look at the needle. All too often people try to jet around the needle cause it's the most exspensive jetting piece but one of the most important. [/QUOTE]
