HS42/018-42K Rubber manifold adapter HSR42

This Mikuni rubber manifold adapter is designed to facilitate the installation of an HSR42 carburetor onto a standard Mikuni 2-bolt manifold. The adapter is constructed from durable black rubber, engineered to withstand the heat and vibrations typical of a V-Twin engine environment while providing a secure, airtight seal. It features a sturdy flange design and includes a worm drive hose clamp to ensure the carburetor remains firmly seated during operation. This component is essential for riders upgrading their intake system to a Mikuni flat slide setup. The adapter is sold individually and provides a reliable interface between the carb and the intake tract.
