Blimey, if he can refurb 750 twin starters with guarentee he is a hero and can have my money! My Project had a slow starter, a pain when trying to set carbs etc. I rooted thru my spares stash and fitted a dirty old starter to see if it was any better. It spins the engine like a washing machine! Best 750 twin starter ever! They are out there and it is possible!!!
