Air/fuel mixture screw for Keihin Butterfly carburetor
Text excerpt from the catalog:
The air/fuel mixture screw is normally plugged off at the factory to prevent for tampering. You won't even find it in a Harley parts catalog. This one fits the Keihin Butterfly carburetor on all Shovelhead 1976-1984, Evolution Big Twin 1984-1989 and Sportster 1976-1987.
