About reeds and valves:
Reed valves are components of fuel supply system in high-performance versions of the two-stroke engine. Valves and reeds control the fuel-air mixture entering the crankcase. As the piston moves up in the sleeve, a vacuum is created in the lower portion of the cylinder beneath the piston. The difference in pressure opens the valve and sucks the fuel-air mixture into the cylinder. As the piston moves down, it raises the cylinder pressure closing the valve to retain the mixture and pressurize it for its eventual transfer through to the combustion chamber.
Brutal pressure takes its toll on light-weight metal valves which are fatigued and develop play. Fiberglass reeds are prone to snapping off and sucked into the engine. Reed valves are less precise as compared to rotary valves because physical inertia causes them to open later than the optimum time. Latest, more sophisticated designs partly address this by creating multi-stage reeds with smaller, more responsive reeds within larger ones that provide more volume later in the cycle.
Nevertheless, current technology favors reed valves almost to the exclusion of rotary valves due to their simplicity and low implementation costs.
