Accidentally stripped one of the bolts on my magneto cover

[Rusty_Nail]

What is a way I can remove the stripped bolt it’s the upper left one. What metric size are they?

Thanks wrench. I'll post one first thing in the morning so you can see.

wrench one more question, can you list a few expansion chambers that will fit a 26" beach cruiser frame? I bought one that was supposed to work and it wouldn't clear the back of my front tire when wrapping around the front of the frame. Thanks!
