KX65 sleeve or replating?????

I got a KX65 and some idiot never put the clip back in one side of the piston wrist pin and the pin ended up grinding a groove into my cylinder. I thought about having it bored but I cant exceed 65cc for the class I am running the bike it. I have looked around on ebay for a used cylinder but they aren't very plentiful. I thought about having a sleeve installed. There are several people on ebay selling sleeves and advertise them as being better then replatting a cylinder. I am somewhat ignorant on 2-strokes and was wondering if anyone had any experience with the sleeving and if it was a good alternative to buying a new cylinder.

I wouldn't put a sleeve on a race bike, I bought my rm85 with deep groves on the cylinder, I gave it to Mr. Zambrana he did his magic to the ports and then sent it to millennium to re do the nickasil for stock piston size. since the first time I rode it I could tell It was way faster than a supersport 65, even I still have stock reeds and pipe. ran it every saturday for a couple of months and then I got 3rd in f2 and f3 at the nationals behind Nate, (Carlo doesn't count) I can assure you I had more power, too bad my suspension was bone stock, but the conclusion is: I've got a super fast 65 by just the engine, no Vforce no pro circuit, and after many many hours without any problem I still very happy with it, I recommend you to do the same, can't remember exactly how much it cost but I think it was a bit under $200 for the replating + whatever Zambrana charges for his porting job, I can find out the prices for you during the week.

Sure Walter, if you could find out what Zambrana charges I would like to know. I tried to call them once and talk to them about rebuilding the motor but I dont speak spanish and they weren't speaking any english
