Carb BSA 441 B44 Victor Amal Mikuni alternative 30mm carburetor PWK JRC 30 900

Steadfast Cycles

SKU: Steadfast Cycle

You will get one PWK 30mm carb. This is a direct replacement for the Amal 930 carburetor. This carb fits BSA Singles, Triumph 650 twins and other British motorcycles with a 30mm Amal carb, or single carb application. This will bolt right on to the manifold flange and use your stock cable and air filter or Triumph TR6.

These will fit a standard flange mount manifold with a hole spacing of 2" on center. Spigot OD is 34mm, carb total depth is 82mm, and the height is 5" minus cable adjuster. The air intake is 48mm OD. This will fit where any Amal 930 Concentric or Monoblock is installed.

If you have a 1977 or later Triumph we have a listing of these carbs for that application.

If you don't have any mechanical aptitude and you think this will go together like a Lego set or like plug and play on your computer then please don't buy these carbs.

Customer feedback:
Dear steadfastcycles,

Got the carb on and the bike started second kick. With some very simple tuning got the idle and mixture set. Now starts first kick. Idles smooth and very slow. Comes off idle great and pulls well.
Thanks again for all your support Brandon.


This carb was designed in Japan for Honda back in the 1970s / We take that carb and we bore it out to 30mm, then we use an adapter so that it can use the stock Amal cable, then we epoxy and set screw the flange on the spigot so that it can bolt right onto you British Motorcycle. it is a good design, i have never seen one fail because of bad quality or design flaw. I have installed and sold thousands of these carbs and they outperform Amal and they fit in spots where the Mikuni won't fit.Every part for this is available through us, even if you crack or lose the bowl for any reason we have those available.
