I got the LA Sleeve 96mm big bore kit with steel sleeve. The first time, the machine shop put it in 90 degrees off and tried to turn it, (they thought the cut outs at the bottom of the sleeve for the crank bearings were 2str porting?). Anyway, that didn't work, the sleeve dropped down and the head gasket blew. They milled it flat and it did it again. They then got me a new cylinder and installed a new sleeve and it did the same thing again?!?!? Any suggestions would be appreciated. I assume this is possible? :whiner:
