N3=04 Throttle stop nut

The Mikuni throttle stop nut is a specialized locking fastener used to secure the idle speed or throttle stop settings on HSR carburetors. This nut ensures that once the idle is set, it remains consistent despite the heavy vibrations of a Harley-Davidson V-twin engine. Manufactured from high-strength steel with a finish designed to resist fuel and environmental corrosion, it provides a reliable grip on the adjustment screw threads. This is an essential small part for maintaining a stable engine speed at a standstill. This genuine Mikuni component is sold individually.
