I'm going to vent to you all, because its late and I'm in my garage looking at my 2002 cr250 back on the stand. I bought the bike lay year and rode the tits off it all winter. Last month a took her down for a new piston and saw that the cylinder was flaking off by on the exhaust port. I knew this was an issue with the hondas so I set out to my local shop to get her fixed up. I talked to my trusted mechanic and he assured me that our local engine builder who has been building motors or 20 years can take care of me. So I hand over the cylinder and a new stock spec wiseco piston and he ordered a northwest steel sleeve. I know there are people who hate on resleeves instead of nikaseal. Nothing but good luck with sleeves here. Until now. I got the cylinder back and everything looked good except for a few nicks in the sleeve where he had gotten a little excited with the dremal. I was a little miffed about it but they where low in the cylinder and he assure me it would be fine. So today I took the bike out today for brake in and after 20 minute of ride time I was blowing coolant on my boot from the head gasket. Bummer. So I called the shop and i went down and had Tom replace it thinking it was my fault. I take it back out and ride for another 20 minutes and hot &%$#@!ing dammit she's leaking again. I was pissed. I got home and took it apart myself and checked out all my clearances and surfaces. The machinist didn't machine the head flat. The sleeve had a high spot that was at least .001 upon more inspection the exhaust bridge port had began letting go metal flakes like the stock cylinder..what the? So here I am, set back 500 bucks with a shitty cylinder and a stock that won't honor its &%$#@! up. Worst part is I've been friends with the guy for along time. All I want to do is ride!!!!
