Any way to tell condition of cylinder without pulling it??

I found a pretty good deal on a 2001 YZ125, that "needs a little work". Says motor starts and runs fine, but it will probably need a new piston/rings, and it will need new sprockets and chain, as well as a new kickstart lever.

Now its a great deal, and I want to hit the woods by January 1st (place we ride is free on holidays). I dont mind getting it a new piston and ring and stuff, but how can I tell if the cylinder and plating itself is any good??? Thats all I am concerned about. I dont care if I need to spend $100 on a piston and ring and c-clip and upper bearing, but I DO NOT want to spend the $300 to replate or sleeve a cylinder.

How can I tell if the cylinder is scratched or the plating chipping?? BTW the price isn't too good to be true, but its good enough that even with replacing these parts its still a good value.

I though a replate required a new piston to be sent in. So 200+100=300.

The problem is its a running bike, but he says it just needs a little work like sprockets and chain, piston and ring, small stuff. The bike looks pretty clean, almost makes me wonder why he wants so little for it (he has the title too). So I cant exaclty come over and tear the top end off his running bike to see if the plating is good.

Oh ok, thought I had heard someone say I would need to send in a piston, maybe it was for boring a sleeve. Well if thats the case then I might just snag it.
