Did I read somewhere that the Vertex piston is stock?

Then Go Fasters should have rings, wrist pin etc. no? Some other supplier for Vertex stuff?

I'm also intrigued by some of the talk I saw about port timing a while back.

As long as it's apart I figured I might as well check and see if it's at least close. Lots of theorizing but I didn't find any concise info on how one goes about checking it or what it "should" be. I measured the single green gasket that was on there and it's about .30mm
