27371-76A Fuel Line Barb Fitting for Keihin Carburetor

Maintaining a Keihin 40mm CV carburetor is much easier when you have access to the right replacement parts. This selection of components from Zodiac covers the essential items that even the factory often overlooks, such as the rubber membrane for the throttle slide and the air/fuel mixture adjustment screw. These parts are designed to fit the 40mm Keihin CV found on 1988–2006 Sportster models, 1990–2000 Evolution Big Twins, and 1999–2006 Twin Cam engines. They also serve as a direct replacement for OEM 27371-76A. If you are running an S&S manifold, remember that specific S&S seals are required for the installation. Keeping your constant vacuum carburetor in top shape ensures smooth throttle response and consistent fueling across all riding conditions.
