Easy buddy. Slow,deep breaths....There ya go.
I'm certainly no expert with mopeds, I'll leave that up to folks like Fred, Ron and Ike.
But I have had stripped out bolt holes fixed on other machines with a Helicoil. It looks sorta like a spring that goes into the hole and gives the bolt something to "bite"against.
I have no idea whether this would be effective in your case but hey, it's a starting point. If nothing else maybe it will at least provide a few, comforting hours of false hope!
