Mini Starter grind :(

Some of those starters came with a oversized mounting hole. Mine did and I had to use a bushing on the one bolt. I don't remember if it was the lower stud or the top bolt. It came with the starter. Loosen it up and see if you can move the starter in and out on the one bolt. This is a easy check and can be fixed without removing the starter if this is your problem. Mine did the samething and I removed my header tube and starter and I wouldn't have had to. Steve
