Frequently Asked Questions

What does the #160 size mean?

Jet size #160 controls fuel flow through the main circuit at cruising throttle. Higher numbers = richer mixture; lower numbers = leaner mixture.

Why would I need larger jets?

Richer jetting may be needed after adding a high-flow air intake, riding at high elevation, or installing an aftermarket exhaust system.

How many jets are in a pack?

Four jets per pack — enough for one carb rebuild with spares or two bikes with stock carbs.

Will these fit my Harley or Indian?

Only if your bike has large round Mikuni carburetors. Check your carburetor type and existing jet markings before ordering.
