Frequently Asked Questions

What does the #167.5 number mean?

The jet size determines fuel flow. #167.5 is leaner than a #170 and richer than a #165 — use it when stock jetting runs too rich or lean.

How many jets come in a pack?

Four jets per pack — typically enough to jet both carbs on a twin-carb setup with one spare.

Do I need a jetting kit or just the jets?

Just the jets. You'll need carb removal tools and basic mechanical skill to pull the carbs and swap the main jets.

Will these fit my Harley or Indian?

Yes, if your bike has Mikuni carburetors with large round main jet seats. Check your carb model before ordering.
