Carb is good to go.
Piston was intact the ring was still on, seized but still there. Circlips were still there. Nothing was in the cylinder the only evidence was the damage.
I'm thought the bottom end bearing went to shit because the con rod was a little chunky after the first cylinder destruction. I put a little pb blaster on it and it was smooth as butter (maybe not the best idea). The exhaust doesn't have anything rattling around. My brother welded a new stinger on it for me because the original was fucked.
The wierd thing is that everything is good to go after I put a new kit on it. I get a few miles out of it, start to tune, look at pipes on treats, then boom, engine peters out and I walk my ass home.
I'm pretty hesitant about cracking the case just because if I'm in there I'm going to do the bearings and seals. I know I can shim the crank but it's going to be a pain in the ass.
