Good luck to ya.

 

Porting a rotary is actually much closer to changing the cam, say in a street port, and similar to changing the cam and the size of the valves with the bridge/peripheral port. The ports control the timing of intake/exhaust much like a two-stroke.

 

thanks guys this really simplified things for me
