  1. i remember seeing a magazine article in the 80's or 90's about an australian guy that merged a few small dirtbike engines to produce the same idea it had a rotary disc valve modified to compress the fuel air and a 4 stroke head and cylinder with the cam geared to run 1:1 it was essentially a supercharged 2 stroke with no ports in the cylinder that used valves in the head.
