Main jet
- Thread starter DAugust84
- Start date
Depends on year,220, 230.
Have to make sure everything else is good.
What makes you think it's rich? Have you done a plug chop?
List ALL of your engine mods, someone will let you know if you are close.
Have you ever done a leak down test?

Filter and pipe IS a mod. Air in, air out. You probably need to be near a 270-260, maybe bigger..
/\ that, maybe even 290/300 depending on current riding temps and elevation.
do not run it again until you plug chop to confirm jetting, or your next question will be...."what piston"
plug chops, the only way to not fry pistons......
