If nothing else it can't hurt acceleration out of a hand launch..
Another thing I noticed in a quick visual, was that the exhaust port is slightly taller, cut in both directions so opens earlier and closes later. I guess I should get my act together and learn a bit more about porting and timing than the meager set of basics I think I sort of know. I'd love to have a go at the .65 P/L and see if I can reproduce some of the changes and gain some top end. It ain't the extra .02 ci that does it all.
Is Harry Higley's book the best reference for two stroke theory? Or.....?
