It features a lightweight die-cast aluminum alloy body for reduced weight and, consequently, slower wear on your intake pipe. It’s worth noting th KEIHIN is known for producing high-performance, easy-to-tune carburetors. This PWK carburetor is a flat-diaphragm model designed to provide better responsiveness when you open the throttle. The finish is, of course, top-notch, and the venturi effect has been very well engineered. The float chamber is equipped with a plug so you can quickly remove your main jet to fine-tune your settings for optimal performance.

On many motorcycles, the factory settings are perfect, but you should still check the color of your spark plug and fine-tune your settings to avoid long-term problems. We recommend this carburetor for street or touring motorcycles. For those who do repeated jumps, we recommend the QUAD VENT model. Below you’ll find an exploded view of the carburetor. If you need a replacement part that isn’t listed on the site, please send us an email, and we’ll add it as soon as possible.

Right or left? This refers to the side of the carburetor where the idle stop screw is located. Choose the same side as on your original carburetor so that the screw remains accessible and the cables and hoses route as before.
