Hello Steve its not a velo clutch it is Scott.(ner the twain shall meet ) Some Scotts have had Velo gear boxes complete with Velo clutch fitted but that’s another story. The Scott clutch is straight forward if replacing just the plates try not to let the clutch sprocket come towards you when you undo the clutch springs it runs on rollers that are best kept in place when you have replaced the plates and springs ajust the spring retaining nuts so as to get the outer pressure plate to run true with the clutch handlebar lever held in and operating the kickstart pedal . The book of the Scott from the 1930s has a page or two with all the gen .others greater than Iwill be able to gen you up. Regards D F.
