I purchased a Sherpa last year with the intention of restoring as I have done a fair few in the past. I am just looking for a little advice as to the definite year/model as there are a few things puzzling me. To start off the bike is sat in a frame believed to be SM but can not confirm, the original frame is supplied which is numbers matching to the engine.
Engine JM-19906685-A
Frame JB-19906685-A
The Number of the frame the bike is currently sat in is 685, no letters just the three numbers and looks to be chrome. Also the bike has what I believe to be an airbox mod which was throwing me off the year and model etc. After some research there seems to a airbox you can fit off a 151/138 model, enables the bike to breathe better. Can anyone shed any light? See attached photos.
Thanks sam.
