Drag? All you're doing is eliminating combustion. The cylinder is still lubed. The piston works against vacuum on the downstroke, but is aided by it on the upstroke.
That's what I meant, "drag" probably wasn't the best word. It would seem that allowing the in. valve open just a crack on intake, and the ex. open during compression stroke would eliminate some excess work but probably to little or no gain?
