Frequently Asked Questions

What does the #132.5 number mean?

The number indicates the orifice diameter in millimeters — larger numbers = richer fuel mixture, smaller numbers = leaner. #132.5 is mid-range for cruise jetting.

How do I know if I need these jets?

If your bike is running too lean or too rich at cruise, or you've added an air filter or exhaust that changed air flow, a jetting change may be needed.

Are these original Mikuni parts?

Yes — genuine Mikuni manufacturing, not aftermarket copies.

Will these fit my Harley carburetor?

These fit Harley and Indian carbs that use the large round Mikuni jet body. Verify your carb model — some Harley models use different jet styles.
