OK sounds like an easy first try steve,so once I take it off,reclock,give it 3 trys in and out to check that is it? Steve I don't believe the stock gears are hyvo,it saids in my manual they are Borg warner,and not even sure the 84 chain I got from cat was a hyvo either,it was 15 wide and 110 bucks,but there 22 top I believe is sentered metal gear,that's the gear I have to put back in if ther are in fact blown,the top gear,which was Yamaha 21 gear.But I have the 15 wide stock 86 pitch hyvo chain and cats 22 top for the stock 41 bottom,if it in fact does need to be fixed.
