this is how it happened. the sleeve is very thin throughout the middle. I took my heat gun and heated the case. the rest just slid out, but you can see there isn't much material in the middle to work with. preheat your motor before pulling this sleeve!! I'm guessing I will need a sleeve and maybe a new piston at this point. any ideas on where I can find them??

definitely wasn't run lean.. everything else looks good. conrod looks like jewelry..
