Frequently Asked Questions

Will these fit my S&S Super E or G carburetor?

These are main jets for S&S carburetors. Confirm your carburetor model and fuel circuit before ordering — main, idle, and accelerator jets are not interchangeable.

What size jets do I need for my bike?

Jet sizing depends on engine displacement, airflow modifications, altitude, and tuning goals. Consult your carburetor manual or a tuning expert to select the right size.

How many jets are in a pack?

Five main jets per pack — enough for multiple tuning sessions or to stock spares.

Do I need to remove the carburetor to change main jets?

Yes — you must remove the carb from the bike and disassemble it to access the main jet cavity. This is not a quick roadside adjustment.
