If you have a few years to kill....Great book on how a 2-stroke really works:

I've read parts of this . . . pretty good description of squish band, port timing, and effect of pipe dimensions. Old school but physics never change.

Yeah, minus the addition of the powervalve, the bike engines are still completely covered. Piped, reed valve, shcunele(sp) style porting.
