Amal Carburettor Parts & Spares
Amal carburettors were fitted to most British motorcycles of the post-war decades, from BSA and Triumph to Norton and Royal Enfield. A worn slide, a tired needle jet or a sticking float is behind a large share of poor running on these bikes, and the fix is usually a handful of small, correct parts.
Obsolete Bike Parts stocks Amal service and repair parts in original and reproduction form, selected to suit the machines we supply every day. Orders go out worldwide from the Netherlands, and we are glad to help you identify a carburettor before you buy for it.
Which Amal is on your bike?
The Monobloc, the Concentric Mk1 and the later Concentric Mk2 are different carburettors with different jets, slides and float assemblies, and bore size and handedness matter as well. The type and size are normally stamped on the body. Read them before you order, because a jet or slide that looks right can still be the wrong one. Twin-carburettor machines add another detail: the left and right instruments are mirror images, so float bowls and some fittings come in pairs rather than as identical parts. Earlier pre-Monobloc carburettors are a separate family again.

Jetting questions
If you are not sure what your carburettor should be running, send us the markings on the body and the details of the bike. We can help narrow it down, although final jetting always depends on how the engine is set up and where it is ridden.
