Common questions

What's the role of the main jet in a carburetor?

The main jet controls the amount of fuel that flows into the engine at mid-range to wide-open throttle. It's a key factor in ensuring your engine receives the correct fuel mixture for optimal performance.

How do I choose the correct main jet size for my V-twin?

The ideal jet size depends on factors like your engine's displacement, air filter, exhaust system, and riding altitude. Consult your carburetor's manual or a qualified tuner for specific recommendations for your Harley or Indian.

Are these jets difficult to install?

Main jet installation typically involves removing the carburetor float bowl. While generally straightforward, it's recommended to consult a service manual or professional if you're unsure to avoid damage.
