You should go down a pilot and main jet size on the '11, assuming they are correct now.

On the '12, re-set the ECU settings by warming up the bike for 3 min, then shutting it off for 1, then starting it back up for 1 min without touching the throttle (at all in any way) so the senors can re-acclimate.
