I don't have anywhere near as much experience as rx4ur7, but I have seen several engines with failed rotors, with the cause clearly being carbon buildup from the 6PI actuators going through that rotor.

I think that the biggest problem that the weight will cause you is the speed that the actuators can open the 6PI. You may notice that your ports open at a higher RPM point than they did previously (there is really nothing wrong with this).

Revving a rotary is fun for a reason, it helps keep carbon to a minimum and it uses the 6PI system, which keeps it from seizing and beginning the carbon-buildup scenario.
