Frequently Asked Questions

What does the 67.5 size mean?

The number represents the jet orifice diameter in hundredths of a millimeter. Size 67.5 is a mid-range main jet for moderate fuel mixture adjustment.

Do I need to replace all jets at once?

Not necessarily. Replace only the jets needed for your tuning adjustment. The 4-pack provides spares and a buffer for different tuning scenarios.

Will these fit any Mikuni carburetor?

These are large round main jets and fit Mikuni carbs designed for that jet style. Verify your carburetor model accepts large round jets before ordering.

How do I know if I need a different jet size?

Jet selection depends on altitude, fuel type, air filter, and exhaust modifications. Consult your carburetor tuning guide or a Harley/Indian shop for your specific setup.
