Answered: Why Aren't Reed Valves Metal?
Sure with the decline of 2-stroke powered ATVs, you don't hear much about the reed valve but one reader wants to know why the petals aren't made out of something that can last forever... like metal:

Best place for metal was on the old rotary valve engines on the early Kawasaki,Suzuki type engines. Actually no force on the metal,just uncovered an opening for the fuel air mixture to enter the cylinder. Precursor to the modern reed valve systems. Many are still out there in rc engines that can exceed 22,000 rpms or more.No fiberglass or any other reed could take that much pressure. Talk is that was where Rotax originally got it's name. Don't know if it's true or not.
