Mikuni HS42/001-CHR-K Chrome HSR Air Box Adapter Kit

The Mikuni HS42/001-CHR-K is a genuine Mikuni chrome air box adapter kit designed to mount a stock or custom air cleaner onto Mikuni HSR-series carburetors. This adapter bridges the gap between the Mikuni HSR smoothbore carburetor and the Keihin CV bolt pattern, allowing riders to retain their original-style air cleaner while running a high-performance Mikuni carburetor.

Key Features:

• Adapts Mikuni HSR carburetors to the Keihin CV bolt pattern for stock and custom air cleaner compatibility
• Compatible with stock Harley-Davidson CV air cleaners and most custom air cleaners built for Harley-Davidson CV carbs
• Also compatible with S&S Shorty air cleaners (minor fitment modifications may be required on some versions)
• Polished chrome finish for a clean, show-quality appearance that complements polished or chromed carburetor setups
• Genuine Mikuni product, manufactured in Japan

Kit Includes:

• Chrome alloy adapter
• 3 stainless steel mounting screws
• O-ring seal

The Mikuni HS42/001-CHR-K is the chrome-finish version of the HSR air box adapter kit, offering the same precise fit and function as the standard kit with an upgraded appearance. Note: For fitment of some S&S Shorty air cleaner versions, minor material removal from the breather or backing plate outer edge may be required to ensure clearance for the carburetor return arm.
