A few days ago I finished fixing a "starter" problem for a friend.......I'm cheaper than a dealership. He said the starter was acting funny, seemed to free-wheel a few times trying to start it. I actually got it to do what he said. I moved the bike back a few inches, in gear, and it fired up. No apparent problem. When I shut it off I heard a "clunk". I'll make this short and sweet. Pull the primary and check the compensating sprocket nut. I could turn it by hand and the sprocket and shaft extension had about 1/4" of free-play. My guess is that the sprocket slid down the extension to the point that the entire primary was in a bind. He also says it shifts quieter now. Just a little tidbit of info to share.
