      JRC carbs

      I recently purchased a pair of JRC 30mm carbs for my '66 BSA A65L. My mechanic just called to tell me that he'd installed them, they were a fine fit and the old girl fired on the first kick. I couldn't be more pleased. Thank you, David J Madden

      JRC 30mm Carburetors - PWK / Keihin - Replace Aam

      GREAT! I'd give the carb 5 stars. Price is right especially with machined adapter that was included and mounted. Only issues I encountered, and this is only if your not very mechanical, are the area for the ball end on throttle cable was not machined out enough for sliding lock to close ( dremeled out, be careful ) and air filter housing is threaded on old Amal so made mounting to clamp on. Also the idle adjustment was adjusted way to high from factory and I believe was causing the motor not to fire right away. Very minor issues for someone with some mechanical ability.

      JRC PWK Carby

      Great carby that works well and is easy to set up. The postage to Australia was way too expensive though.
