Hello All. Cannot get my left side head to seal and I'm out of ideas. The bike had a stripped head bolt when purchased and I helicoiled it no problem. I don't think it was leaking prior to teardown but the center main seal was which has since been repaired.

The leak is occurring in the same general area as the broken bolt. Relapped the head and jug, fresh gasket, still leaking. No cracks found, bolts are not bottoming out, torque is correct. In my frustration I even tried Permatex Copper Spray - still nada.

The sleeve is slightly higher than the casting but as I recall so was the right side. This is something I have never seen on any of my 2 strokes but this is my first Suzuki. Should it be higher or could the sleeve have slipped?

Suggest you skim the block (with liners fitted). Be cautious doing this. You will need to check deck height to ensure piston will not hit head afterwards. If it is too high, you will need to get the squish band re-cut. Chris Applebee did this on a GT250 for me a while back.
