I also have a rear hub question. I am re-building an A10 with a dubious heritage and seem to have an oversized rear hub. The RHS is markedly domed and there is no room for the standard spacer between the swing arm and the hub. The wheel is impossible to remove/reinstall with the sprocket on the swing arm, as described in the Haynes manual, without forcing the swing arm apart. Has anyone come across this problem? Looking at images of other A10's the rear hub RHS appears to be flatter than mine.
