Yeah, what I have understand, Kiwis and Aussies used to use them alot, cause they banned PPs...
I reckon that those can flow almost as much that PP flows.

Part of the inlet port is always open on the rotor housing, plus they cut from both ports into the housing so it definately has more area than a PP. Carl show me of his and I think there was only 40mm in the centre of the housing left
You have to use 1 piece apex seals when you go that far, that just makes them hard to start.
I tried working out the inlet degrees timing ages ago and couldn't get my head a round it, my dad could but he's a massive 2 stroke guy.
I think the inlet opening time on a PP would be 359* as it essentially never shuts
With the monster port it would prety much be the same.
IT would be interesting to know the surface area of a monster port versus the area of the port going into the housing
