I have a HMF slip on silencer with 12 vents in my airbox. What is the correct jetting for this setup? Has anyone been changing the pilot jet or needle?
You can't just go a certain size and then go down, u go up until it skips at full throttle. Then u go down one size and ur jetted good. Also, if it skips slightly when going from 1/8 throttle to 1/4- throttle then ur lean in the midrange, that means u ower the clip to raise the needle. Hope i helped.
