Looking for a high-performance, cost-effective replacement for your Amal 930 or Mikuni carburetor? The 30mm JRC Carburetor is an excellent choice, offering a direct bolt-on solution for a variety of British motorcycles. This carburetor features a smooth-operating chrome slide for reduced wear and an integrated choke lever for easy starting.

Adapted for British Bikes:

These carburetors, also known as PWK or Keihin carburetors, are expertly adapted by JRC Engineering specifically for British motorcycles.

Jetting Information:

Your JRC Carburetor will arrive with the following jets pre-installed:

• Main Jet: 125 (T120/T140 twin-carb 650/750 models use a 130 main jet)
• Pilot Jet: #38 (T120/T140 twin-carb 650/750 models use a 35 pilot jet)

An additional jet kit is included, containing:

• Main Jets: 130 and 140 (TR6/TR7 single-carb 650/750 models use a 140 main jet)
• Pilot Jet: #35 (TR6/TR7 single-carb 650/750 models use a 38 pilot jet)

Recommended Jetting:

These are general recommendations; you may need to use different jets based on your specific bike:

• Twin Carburetor Models (e.g., Triumph Bonneville, BSA A65): Use a P26-130 main jet (comparable to an Amal 190).
• Single Carburetor Models (e.g., Triumph TR6 Tiger, BSA B40, B50): Use a P26-140 main jet (comparable to an Amal 230).

Additional Jets and Resources:

We stock a wide range of jets from the equivalent of an Amal 170 to 240. Installation instructions and a parts list for JRC Flatside Carburetors are available below.

Note: There are no returns on carburetors, electrical items, full frames, hardtails, or made-to-order items (such as magnetos) unless there is a manufacturer’s defect.
