These JRC Carburetors are 30mm, and are a great, economical alternative to Amal 930 carburetors or Mikuni carburetors. These are a direct bolt on replacement for your stock Amal, and will use your stock throttle cable. These feature a chrome slide for smoother operation and less wear, as well as an integrated choke lever on the body of the carburetor for easy starting.

These are also known as PWK or Keihin carburetors, they are adapted for use on British motorcycles by JRC Engineering. These 30mm carbs are supplied with with a 130 main jet and a 26 pilot jet installed and there is a 140 main and 35 pilot included in the box as well. These 30mm models are great for your British twin cylinder motorcycle. For twin carburetor models such as Triumph Bonneville or BSA A65 you would want to use a P26-130, comparable to an Amal 190 main jet. For single carburetor bikes like the Triumph TR6 Tiger, you would want to use a P26-140 main let, comparable to an Amal 230 main jet. This would also work great on your BSA B40 or B50.

We have a wide arrange of jets available from the equivalent of an Amal 170 – 240 in stock. You can find installation instructions and a parts list for JRC Flatside Carburetors here. Sold Individually.
