Thank you for that, nice info. One other question on this similar topic, I have a spare set of cylinders that I suspect are early H2 cylinders, well, before the H2B anyway, how would I tell these apart? Port height meaurements or?

You can do a quick check by the transfer cutouts in the sleeve. Early is the cutout are way below the gasket surface (cylinder upside down), 2nd Generation has a pretty good angle on the cutout, and 3rd gen his the cutout a ways below the gasket surface.

So Kawasaki's way to reduce power was to choke off the transfer inlets, and the didn't really change the port timings?
I was asking about port timings as I am making hydroformed 304 stainless chambers for my H2B and going through the length details with someone for the design.
