Frequently Asked Questions

What size jets do I need for my bike?

Jet sizing depends on your carb model, altitude, and fuel mixture target. Check your carb manual or consult a tuner before ordering.

Why are these sold in a 4-pack?

Four jets allow you to test different sizes or keep spares on hand during carburetor tuning.

Will these fit Harley and Indian carburetors?

These fit Mikuni carburetors commonly found on V-twin bikes. Verify your carb brand and jet type before purchasing.

Are these the same as OEM jets?

These are genuine Mikuni manufacture. Compatibility depends on your specific carb model — not all V-twin carbs use Mikuni jets.
