does a 81 KTM 250 piston have one or two piston rings?  The top of my piston is damged and I am trying to figure out if the very top of my piston is comming apart or if it is a smashed ring. I have another ring below this area but the place I am talking about is right near the crown.

The 81 has one ring. the older 2 ring pistons will work though.
