I found a nut laying in the tray under the seat. I had been working on the bike lately and wondered where it came from ? After a few minutes of wondering . I thought it was an extra ...so I put it in my " stuff box" for the 650. then a week later the seat pulled off in my hand when I grabbed it ...Guess what ? the nuts under the seat holding the seat on came off . I never thought to check them because " out of sight out of mind " ... Anyone else have any " interesting stuff " fall off ?
