232245 Replacement Parts O Ring Choke Cable to Carb Body

This Mikuni O-ring is specifically designed to seal the connection between the choke cable and the HS40 carburetor body. By preventing air leaks at the enrichment circuit, this small rubber seal ensures consistent starting and smooth warm-up cycles for your Harley-Davidson. Over time, heat and fuel exposure can cause original seals to harden or crack, leading to erratic idling. Replacing this O-ring during cable installation or carburetor service maintains the vacuum integrity of the intake system. As a genuine Mikuni component, it offers the exact dimensions required for a leak-free fit on the HS40 SmoothBore series, supporting the carburetor's reputation for excellent throttle response.
