Iím not sure if itís any consolation but there have been about 6 or so riders who have experienced the same problem with a side stand bolt (or both) backing out.
Iím surprised they didnít apply LocTite at the factory.
Glad you caught the bike before it did any more damage.
So, lemme get this straight.
I twist this little tube, it gets loud, I go forward really fast and it makes me smile...is that how it all works?
