Frequently Asked Questions

What does a main jet do?

The main jet controls fuel flow in the mid-range and high-throttle engine operation. Changing jet size fine-tunes your air-fuel mixture for altitude, temperature, and engine mods.

Why buy a 4-pack?

You get spares on hand for different riding conditions, or to share across multiple Mikuni-carb bikes.

Will this fit my Harley or Indian?

Only if your bike runs an original Mikuni carburetor. Most stock Harleys and Indians use proprietary carbs — verify your carb brand and jet body style before ordering.

How do I know if I need a size #95?

Check your current main jet size. A #95 is a mid-range size; larger numbers = richer mixture, smaller numbers = leaner mixture. Consult your carb manual or tuning guide for your setup.
