Carb BSA 650 Thunderbolt Amal Mikuni alternative 30mm carburetor PWK JRC 30 900

You will get one PWK 30mm carb. This is a direct replacement for the Amal 930 carburetor. This carb fits and is jetted for BSA 650 Thunderbolt. 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. 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.
