Frequently Asked Questions

What size is a #110 jet?

#110 is a mid-range main jet size. Larger numbers = richer mixture; smaller numbers = leaner. Check your carb manual for the correct size for your engine and riding conditions.

Why buy a 4-pack?

You get spares for future tuning or maintenance. A 4-pack allows you to test different jet sizes and keep backups on hand.

Do I need any special tools to change the jets?

A small screwdriver or jet tool is helpful to remove the bowl nut and access the main jet. Refer to your carb manual for specific instructions.

Will these fit my stock Harley carburetor?

These are genuine Mikuni jets for Mikuni carburetors. If your Harley runs a Mikuni (not OEM Harley Keihin), these will fit — verify your carb model first.
