I have a question for the engine gurus. I ran across a thread where someone was using a ZDZ motor today. ZDZ is one of the manufacturers that uses rotary valve induction and I think the XYZ 50 a few years ago used it as well. What are the advantages of rotary valve inductions and what changes in terms of throttle response, top end, torque, etc. if you had two engines where one was a reed valve and the other rotary valve?
Just curious.
