The main jet controls the volume of fuel delivery in your carburetor from a little less than 1/2 throttle to wide open.

If you've upgraded your carburetor, air intake, or exhaust, you will find you're running leaner. A larger main jet can help restore the correct air/fuel ratio in your system.

Most stock carburetors come with a main jet between 108 and 115. With a UNI filter upgrade, most systems will need a main jets between 120 and 130, depending on your elevation and vehicle setup.
