Frequently Asked Questions

What does a main jet do?

The main jet controls fuel flow through the main circuit at cruise and part-throttle speeds. Larger numbers (like #162.5) enrich the mixture.

How many jets do I need?

Each carburetor has one main jet. This 4-pack provides spares for tuning adjustments or service on multiple carbs.

Will these fit my Harley carburetor?

Only if your Harley uses a Mikuni carb (stock or aftermarket). Check your carburetor manufacturer before ordering — Shovelhead, Pan, Twin Cam, and other models may use different carb types.

What's the difference between #162.5 and other sizes?

Higher numbers (like #162.5) flow more fuel — a richer mixture. Lower numbers lean out the fuel delivery. Your jetting depends on altitude, temperature, and engine setup.
