Amal 932 Premier Concentric Carburetor Set – Norton Commando – Pair Left & Right (932/300 932/301)

Amal 932 Premier concentric carburetors Norton Commando

Amal 932 Premier concentric carburetors Norton Commando — a matched left and right pair ready to bolt onto your Commando and transform the way it runs. These are genuine Amal Premier Mk1 concentrics built in England, not copies or reproductions.

Why Upgrade to Amal Premier Carburetors?

The Premier series is Amal’s modern evolution of the classic Mk1 concentric design that Norton fitted from the factory. Every weak point of the original has been addressed: the throttle slide is hard-anodised for dramatically longer wear life, the float is an ethanol-resistant Stanjo stay-up design that won’t sink or permeate on today’s pump fuel, and the needle valve is Viton-tipped alloy for rock-steady fuel levels. The result is a carburetor that looks period-correct on your Norton but delivers noticeably crisper throttle response, better fuel economy, and a stable idle you can count on.
