Each carburetor is pre-jetted with a proven baseline setup to provide an excellent starting point.

Spare Main Jets (165 & 175). Spare Pilot Jets (45 & 55). Please verify all measurements, specifications, and fitment information before purchasing. This carburetor is intended for high-performance and modified applications. Due to the wide variety of engine combinations, installation may require custom jetting, tuning, or minor modifications to achieve optimum performance.

Warming the boots with a heat gun or hot water will typically restore flexibility for easier installation.
