Well I went to rebuild my top end in my 86 kdx200 and I was dealt some bad news. Apparenty the person before me bored it out so much that they ended up going with a 250 piston. I had it miked and it was 72 thou over. Turnes out the sleev is soooooo thin it is going to need a new one. My question is do I put it all back together and just sell it and buy a newer kdx or is is worth it to fix it. I bought the bike for 300 bucks and I have put a few hundred into it since I bought it and I am not sure it is worth the extra 400 to get it resleved.
