Motorcycle Carburetors

MOTORCYCLE CARBURETORS FOR TRIUMPH, BSA AND HARLEY-DAVIDSON BUILDS

Carburetor choice on a vintage build comes down to the platform and how far from stock you want to run. On a Triumph or BSA, the Amal concentric is the period-correct choice and the JRC flatside is the modern alternative that addresses the Amal's known weak points. On a carbureted Harley-Davidson Sportster, the S&S Super E is the standard upgrade over the stock Keihin or Tillotson. This collection covers all three directions with carburetors stocked and ready to ship.

TRIUMPH AND BSA CARBURETORS

Three options for Triumph 500, 650, and 750cc builds:

• Amal 930 MK1 Premier: The aluminum 30mm concentric carburetor in single and matched pair configurations. Available as a single for TR6 and TR7 Tiger applications and as a pre-jetted left and right set for T120 and T140 Bonneville. The Amal 930 is the direct replacement for the carburetors these bikes left the factory with. Among the most reviewed carburetors in the collection.

• British Standard JRC 30mm Flatside: The most reviewed carburetor in the collection with 32 to 37 reviews depending on the listing. The JRC is a PWK-style Keihin-based flatside designed as a direct replacement for the Amal 930 and Mikuni. It addresses the fuel delivery inconsistencies of the original Amal design without requiring manifold modification. For twin-carb Bonneville and BSA A65 builds the recommended starting main jet is P26-130, equivalent to an Amal 190. For single-carb TR6 Tiger and BSA B40 or B50 builds the recommended jet is P26-140, equivalent to an Amal 230. A matched pair set is also available for 1979 to 1982 Triumph T140 750cc bikes. The JRC 26mm version covers applications originally running the Amal 626.

• Wassell 930 Right Side: 30mm concentric Wassell carburetor for Triumph, BSA, and Norton in right-side configuration.
