I would like to measure a G62. I just couldn't imagine its more than 9.5:1 Thats typically around the std for general purpose 2 strokers.

I buy 110 and 116 for my drag cars but just dont want to give someone an excuse when thy see that old g62 go skyward like a bottle rocket.

My 62 is already ported so buying that new cylinder would mean having that redone as well. That and a pipe would be awsome. The next limitation is the carb. I wish i new of the next biger bore size that would fit the bolt pattern. Wiseco could custom cut a piston also for compression. If you do this you'd might as well over bore it. I KNOW on my motor that would put me around 3lbs maybe a tiny bit over. Probably around 68-70cc. I cant remember how much material is ther to work with.
