Yeah that was something I was wondering about as well. Since an amount of fresh air and fuel flow straight through the cylinder when both ports are exposed I would think that the AFR would be thrown off to some degree. Due to this, I would imagine the sensor would read a rich mixture in comparison to a four stroke engine.

i'd imagine it would read a lean mixture since a good amount of unburnt fuel and air is sucked back in the motor through the pipe.
