The other day while trying to change my front sprocket to a 15 tooth. The dimples in the flange on the nut that holds the front sprocket on. I had them bent back up and went to turn the nut off the threads for the nut stayed on the shaft and it messed up the treads on the shaft I had a 1/2 in ratchet on it and it didnt take much pressure to take it off for about 7 or 8 turns then it stuck but all the threads are messed up a little. The yamaha shop said that it might be covered under warranty. I am a mechanic at a factory i deal with nuts and bolts all the time I turned it the right way. Anybody else ever had this happen? any ideas why? The mc shop had it now but no word yet they are closed on mondays. I know I turned the nut right way to take it off.
