OVERVIEW

This complete carburetor rebuild kit restores precise fuel metering, stabilizes idle speed, and eliminates vacuum leaks across vintage Harley-Davidson motorcycles. Designed specifically for butterfly-style and CV-style Keihin carburetors, it supplies every essential seal and clearance component needed to return your fuel system to factory-calibrated operation for 1976–1989 models.

ENGINEERING & PERFORMANCE

The assembly delivers consistent airflow and fuel delivery by replacing hardened seals and clearing micro-passages that commonly cause hesitation and hard starting.
