Motorcycle Fuel Petcocks – Vintage OEM & Aftermarket Fuel Valves

Shop motorcycle fuel petcocks for vintage restorations and fuel system repairs. This collection includes OEM and aftermarket fuel valves designed for classic Honda, Yamaha, Suzuki, and Kawasaki motorcycles.

A worn or leaking fuel petcock can cause fuel starvation, flooding, leaks, or inconsistent carburetor performance. Replacing a faulty motorcycle fuel valve restores proper fuel flow control from the gas tank to the carburetors, ensuring reliable starting and smooth engine operation.

Our inventory includes manual fuel petcocks, vacuum-operated petcocks, rebuild kits, and model-specific replacement fuel valves — all selected for accurate fitment, proper flow rates, and dependable performance across stock and restored vintage motorcycles.

Old Bike Barn specializes in vintage Japanese motorcycle parts with trusted OEM and aftermarket components curated by riders who wrench and maintain classic machines.
