Hi from Wales, UK! Just bought a 1980 Triumph Bonneville T140E which has the Amal Mk 2 concentric carbs. Your excellent video is just what I wanted; didn't see any others on the Mk 2's on You Tube. Owned a Norton Commando Mk3 for years, but that has the Mk 1 Concentrics, so Mk 2's are new to me! So thanks for taking the time and trouble to produce a great video! Ken.
