237958 Rubber Carburetor to Manifold Mounting Flange for Early Styl

This rubber mounting flange from Mikuni serves as a critical interface for securing carburetors to the intake tract. Designed with slotted mounting holes spaced at 2.859 inches (72.6mm) center-to-center, it offers the flexibility required for various custom Harley-Davidson fuel system setups. The heavy-duty rubber construction is formulated to resist degradation from fuel and oil while providing necessary vibration isolation for the carburetor. This helps maintain a stable float level and prevents air leaks that can cause lean running conditions. Mikuni’s expertise in performance induction ensures that these flanges provide a tight, reliable seal for both HSR series carburetors and other custom applications.
