Branson,
aircooled two strokes have pinned piston rings (perhaps the key he is referring to but I think he is talking about the land) to keep the gaps from lining up while the bike is running. Two stroked run such a loose tolerance (as compared to 4 strokes) that the initial break in is vital to engine life.
McB,
First which ring drifted? The first thing I thought of was the gap tolerances are out (if a ring has too much gap then as soon as you fire it it will want to fold on itself), the second I though is that the ring itself is out of spec and you need a new ring, Third I thought is that the ring land is damaged. Once the ring has "drifted" or otherwise bent then it is junk and you need a new ring - you can't use the old one.
What model suzuki is he using pistons from? T250? GT380?
