Frequently Asked Questions

What size jets do I need for my S&S carburetor?

Jet size depends on your engine displacement, altitude, and fuel type. Consult S&S documentation or a carburetor tuner to determine the correct main jet size for your bike.

How many jets are in a pack?

Five main jets per pack — enough to keep spares on hand or tune multiple carburetors.

Is installation difficult?

Main jet replacement requires removing the carburetor bowl and unscrewing the old jet. Most riders can do this with basic hand tools, though professional tuning is recommended.

Will these fit my S&S E or G carb?

Check your S&S model number and carburetor documentation. Main jets are model-specific — confirm compatibility before ordering.
