after 300 miles on my new engine build the headgasket blew. L.A cylinder sleeves installed by the same machine shop I always use. I'm running wiesco 80mm pistons. you can see near all the stud holes the gasket was leaking. these bigger sleeves go right to the edge of the locating dowels. I also noted the sleeve is just a hair lower than the jug. any ideas as to the cause of failure? I also want to add that after 100 miles the left inner stud kept coming loose, even after a proper retorque. I was getting compression out of the hole. another member on this site had the exact same problem but has failed to respond to me.
if you guys need any other photos or better pics just let me know.
also when the bike was running, everything seemed good, nice idle, plugs had a nice coffee color, good power, etc.. then the gasket let loose.
