Frequently Asked Questions

What does a main jet do?

The main jet controls fuel flow during cruise and part-throttle operation. Larger numbers (#97.5 vs. #95) richen the mixture slightly.

How many jets are in a pack?

This is a 4-pack — enough for one or two carburetors depending on your bike's setup.

Will I need different jets for altitude or fuel type?

Yes. Altitude and fuel octane can require jet changes. If you're retuning, consult your carburetor manual or a tuner.

Are these genuine Mikuni or copies?

These are genuine Mikuni OEM jets manufactured in Japan and distributed by Western Power Sports.
