Eric Gorr did a cylinder hone for me and confirmed the GG 125 were interchangeable with the YZ125 power valves. I did not find out which specific years but after looking at some on Ebay. There appear to be two possibilities. They look like the ones from 1997 to 2004 or from 2005 to present.

Why don't you ask Eric Gorr again?!
I'm very interested in the result.

The main parts are the same if not very very close but I did notice small differences in the spring like things that close the power valve. I have one in my garage. I'll try to take pictures tonight and post them.

Sorry. I can't seem to find the cylinder. My friend must have taken it back.

It was 2 yrs ago. While Eric has a fantastic memory, it is probably better to compare what you have to both the two versions I referenced (1997 to 2004) or (2005 to present) and buy the matching pieces.
