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

If you need help with tuning, send me a message. I can recommend a jetting setup that will get you close and can also supply additional jets for fine tuning.

Please compare your original carburetor dimensions before purchasing. This carburetor is intended for modified engines and may require custom jetting or minor installation changes depending on your application. 1 × Aftermarket Keihin-Style 40mm Bored PWK Carburetor. 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. Some older motorcycles and ATVs may require heating the original intake boot and/or airbox boot during installation. Rubber hardens with age, making installation more difficult. Warming the boots with a heat gun or hot water will typically restore flexibility for easier installation.
