That's great! I was at Greenbo yesterday. Nice place.

So anyways, I got my new rings and seals in today. Unfortunately I didn't realize how fragile the rings are. I stretched the first one out to put it on and it snapped in half. Unbelievable

Did you buy original Yamaha rings or aftermarket? It does make a differance. And be more carefull next time

Just kidding, good luck on your build

Mike, I'm rebuilding an 82 G1 also. It has J1700 stamped on the cylinder and I can't find a head gasket to fit. I've ordered three and they are all too big. Looks like your cylinder is from a later engine so you shouldn't have the same problem. Also the reed gaskets are too big. Good luck on yours.

I'm getting closer. Can anyone tell me the torque specification for the head bolts?

Initial -14 ft lbs, second-18 ft lbs and crisscross the tightening sequence.

All back together. Compression is the same. Still runs great, but no improvement in the compression.

I checked the crank seals when I had it apart and they looked fairly new and no leaks.

Still smokes the same also. I guess it's just normal??
