HS42/018-45 Rubber manifold adapter HSR45

The Mikuni rubber manifold adapter for HSR45 carburetors is a necessary component for mounting your performance carb to a stock Mikuni 2-bolt manifold. Made from high-grade black rubber, this adapter is built to resist fuel and heat degradation while dampening engine vibrations. The kit includes a worm drive hose clamp to ensure a leak-free connection between the carburetor and the manifold. Mikuni hardware is preferred by builders for its precise fit and long-term durability in performance applications. This adapter is sold individually and is a key part of a custom intake configuration.
