Cycle Craft Carburetor Rebuild Kit 76 78 Harley Keihin Butterfly Japan Made Replaces 27006 76 DS 289099 Viton Needle OEM Quality

OVERVIEW

This complete carburetor rebuild kit is engineered to restore precise fuel metering and steady idle performance on vintage motorcycles while eliminating diaphragm and seal-related leaks. Manufactured to Japanese tolerances, the kit supplies high-density Viton needle assemblies alongside precision gaskets and seats designed specifically for standard Keihin butterfly units. It serves as a direct replacement part for 1976 through 1978 Harley-Davidson motorcycles.

ENGINEERING & PERFORMANCE

The included Viton needle assembly outlasts traditional neoprene fittings by resisting ethanol degradation and preventing internal fuel seepage under vibration. Precision-cut jets maintain consistent airflow-to-fuel ratios across full throttle ranges, delivering predictable throttle response without hesitation or flooding. Every O-ring and seating gasket matches OEM-style dimensions to ensure leak-free compression during repeated heat cycles. The kit’s model-specific valve sizing guarantees factory-equivalent float chamber regulation for stable off-idle pickup.

WHY RIDERS CHOOSE THIS

Riders select this rebuild kit when factory needle wear or degraded gaskets cause rough idles, hard starts, or intermittent stalling. The upgraded Viton needle eliminates the most common failure point in aging Keihin valves, keeping the float chamber at steady pressure without leaking fuel past the seat. Each included gasket meets production tolerances, which prevents vacuum loss and keeps air-fuel mixing predictable from cold starts through warm running conditions. Because every component matches the diameter and taper of the original parts, riders can rebuild the carburetor with confidence that performance will return to factory baseline.
