Air/Fuel screw help.

Where do i adjust my air/fuel screw to.. All the way in and back it off 3 full turns?

2003 Kawasaki KFX 400. With full CT racing exhaust and a jetted carb with155 main. Uni foam filter with air box lid on. Nothing special.

Careful not to tighten it down too tight, you can break the tip off. You will probably be at 2.5 to 3 turns but I'm sure things like elevation could make a difference on that.

Do you have any mods done to the machine, If you have aftermarket exhaust and air filter with the lid off it could be 3 - 3 1/2 turns out for some machines all depending on what you have done to the bike.

If you turn it out past 3 turns, you probably should move up a jet size. The tension on the spring is too week at 3+ turns out and the screw can vibrate loose. Stock is 22.5. Going to a 25 is the next step.
