My 1971 Vespa 125 GTR keeps mangling the speedo drive.
I don't have any washers on the drive gear but the parts manual shows 2 small washers (No's 41 on diagram) and 1 slightly larger one (No 43).
Could this be the problem or is it something else?
If I need these washers does anybody know where I can get them?
Any help gratefully excepted.
