I was thinking about this and I have a couple theories.

Is it possible that the AFR for your rotors is different, that one rotor is running rich and the other lean?

Typically the wideband port favors one rotor exhaust in what it reads (although not true on a turbo).

Does the wideband dance at all? One rotor may not be burning the fuel at all occaisionally, dumping raw fuel out the exhaust. I have seen engines with a weak face smoke white with fuel mist.
