I have no data on those pieces. I have never had anything but praise for
Racing Beat products. At the least talk to them, and order the tech manual if
nothing else. It is a "Must Have" for rotary people.

You can do the Pports with a drill press and a die grinder, or even a hand
drill. Get a big degree wheel and a dial indicator and jump in. Try some junk
housings first.

The picture is of a rotor at BDC on the intake stroke. Note the intake ports
still open. So intake closing points are reported as "after bottom dead
center"  ABDC. Just like a four cycle engine.  It is a very easy engine to work on,
and I find it a fun thing to do. Read Paul Yaw's tech articles and if you
cannot gather it all in I will help you (or anyone). The direct relationship with
the four cycle functions is difficult to see. Once you get it. Like riding a
bicycle, you will never forget it.
