Frequently Asked Questions
What does a main jet do?
The main jet controls fuel delivery at cruise and mid-range throttle. Larger numbers (#112.5) richen the mixture; smaller numbers lean it out.
How do I know what jet size I need?
Check your carburetor's current jet and your bike's manual. Dyno tuning or plug reads help determine if you need richer or leaner jets.
Why buy a 4-pack?
Four jets let you keep spares on hand and test different sizes without ordering multiple times.
Will these fit my Harley or Indian?
Yes, if your bike runs a Mikuni carburetor. Verify your carb model before ordering — not all V-twins use Mikuni.
