I believe that picture 2 are the components required? I am writing in hope that you can assist me with tracking down a complete clutch/breakdown/parts list for a model H Sturmey Archer CS 3 speed gear box as this is the last component required for my restoration? Also are you able to tell me what type of carburetor is used on this bike.Īppreciate your time and any information you are able to provide.Ĭurrently this is all we have: Triumph CN 500cc Firstly do you know if it is only the CN and CSD that have interchangeable part with the exception of engine and gear box. Have recently bought a Triumph CN 500 1929 to restore, currently a basket case, about 65% complete. Was wondering if you could assist me with some information.
