All the idea of using reed valves would do is improve the low end torque -
exactly what we want, while staying open at high speeds to reduce
obstruction - which we also want. If they lock open at 2000 RPM on a 2
stroke you should get some effect up to about 4000 RPM on a 4 stroker -
which sounds pretty good to me.
