Thanks everyone for your replies,.. yep I was afraid the kit is toast. I will try to post pics of the piston underside and inside of cylinder maybe tomorrow after work. For me the bigger question is now if I buy another kit - how do I prevent this in the future? Some things I was already somewhat aware of but didn't bother doing:

1) better head, water-cooled or not, Polini?

2) better carb (Dellorto 21mm PHBG or Mikuni VM20?)

I know stock barely does the job w a 70cc, maybe I was running lean?

3) better intake than stock?

4) I never smoothed-down the sharp edges on the cylinder ports, didn't know that might be a big deal?..
