So, some not so great results today. First thing I did was check the compression. Couldn't get the engine started (never good) so I had to check it cold. 125 cold on all cylinders except #1 which was about 70 pounds. Really not good! Pulling the head off tomorrow to visually inspect. Hoping for just a bad ring or something. Motor isn't locked up and as I said ran like a champ for 5 miles coming in, so I'm hoping the thing doesn't need a full rebuild.

Well, I pulled off the head, no visible damage in the cylinder or piston. Hoping it's just a bad head gasket, although that looked ok. My mechanic is coming tomorrow to have a look. Guess it's a good thing I didn't find a bunch of metal shavings and a scored cylinder wall in there!

I've replaced the head gaskets on both sides now. Neither looked damaged but the compression came right back up after replacement.

I assume it is a two stroke.
