Toasted engine!

I had that happen once when I lost a ring retaining pin. I now JB weld those pins if I can remove then with a pair of pliers.

Spray some aluminum paint in the engine to fill in the scratch`s in the cyl.....Plus jb welding the ring together and you should be set.....lol.....

I haven't had the cylinder off my Skyhawk 49cc mill, do these things have pinned rings? It looks like your ring might have turned on the piston, most two strokes I've been around have a pin in the groove to prevent the ends of the rings from getting caught in the intake or exhaust ports.

Yes they are.....And I`ve almost messed up my self by miss aligning the rings....Might be what happened....

At least put a sheet over the head. No one wants to look at a dead body.

That's pretty funny Pablo, I like that!

Just so everyone knows... I've never once taken the head off the engine in the 2.5 years that it's been on the bike.
It could've been the ring pin, who knows? I think the old man just couldn't take the extra high revs...

Pretty difficult to say but I'd bet the staking pin came loose. Can you get the piston out of the bore if you punch the ring end back in?
