While I'm waiting on parts to replace my cam chain guide, etc., I thought I'd tackle the starter gear issue. Does the grind/spin thing. The PO replaced the #4 gear with what may be a Mike's XS or similar aftermarket gear. Clip only has about 4 lbs of pressure so that is most of the issue. While cleaning the parts I noticed that inner teeth on the aftermarket are cut differently (first photo) than on the stock gear (second photo). Any thoughts on why this is like that. Also, I picked up an original Yamaha gear in nice condition, except that some of the black material is a bit chipped (second photo). How much does that matter? I'm thinking of trying the original gear instead of the aftermarket one.
