Quality reproduction of the 40mm Keihin Constant Vacuum with accelerator pump. This is the most frequently used carburetor in the V-Twin industry and a great solution for many stock and custom applications. Comes with a 185 main jet and 45 slow jet installed. All parts are interchangeable with OEM except the throttle cable bracket. Note: This carburetor is designed for vacuum operated petcocks. It is therefore, like late-model OEM CV carbs, not equipped with a floatbowl overflow system
