Frequently Asked Questions

What size orifice do these jets have?

These are #.078 main jets — the orifice size controls fuel flow at cruise and steady throttle.

How many jets are in a pack?

Five jets per pack — enough for one carburetor with spares, or multiple carbs if you're tuning a fleet.

Will these fit my S&S carburetor?

Yes — these are direct-fit main jets for S&S carburetors. Verify your carb model uses the same jet seat before ordering.

What's the difference between main jets and pilot jets?

Main jets control fuel delivery at cruise and load. Pilot jets handle idle and low-throttle operation. Both may need adjustment for optimal tuning.
