About This Product
The Mikuni pilot air o-ring is a critical sealing component for the carburetor's idle circuit. This small, fuel-resistant elastomer ring prevents air from bypassing the pilot screw, ensuring that the idle mixture remains exactly as tuned. For Harley-Davidson riders using Mikuni HSR carburetors, a perished or flattened o-ring can lead to difficult starting and inconsistent idling. Replacing this seal is a standard part of any carburetor maintenance routine to ensure peak performance. This genuine Mikuni replacement part is sold individually.
Manufacturer part number: N133037.
