Hello Steve,
I have an '80 250 enduro here which needed rings, but from memory I think they are .8mm thick and hard to get. I went through the Wiseco book and ended up getting a set of four stroke rings the right size & thickness, just threw away the oil ring. All good. I could find the part number if you like. By the way, given that the bike is about number 30 on my list I would probably sell it if anyone is interested. Got it running but that's all so far. I was going to put the engine in a V75 frame I have. I also have a VR250 engine which can probably go.
Cheers,
K

thanks for that k , rings on this one are the same pissy thin things , they were seized in , i got them out , filed the really ugly bits off the piston , got a set of 72mm wiesco rings off a dead bully piston , used the angle grinder on them till they fitted the groves, ground the ends till they would fit in the bore ,gave it a quick hone , slammed it together , must have 200psi , stuck the bare engine on a rag on the concrete , gave it a shot  in the intake , 6 kicks and it,s belching out smoke and noise (that,s full noise) , no 2000 dollar engine rebuilds here !
