Frequently Asked Questions

What does jet size #117.5 mean?

Jet size indicates fuel flow rate at mid-to-high throttle. Larger numbers = richer fuel mixture. #117.5 is a mid-range main jet commonly used in stock Harley and Indian carbs.

How many jets are in a pack?

Four jets per pack — enough to replace main jets on two carburetors with spares, or to experiment with different sizes.

Will these fit my Harley or Indian?

These fit V-twin carburetors that accept large round Mikuni jets. Verify your carb model accepts this jet style before ordering.

Do I need special tools to install a jet?

Most jets install by hand into the carburetor body. You may need a carburetor removal tool if you need to access the bowl, but jets themselves unscrew easily.
