Hard to see what the AFR numbers are on the bottom box of your graph. Also, depending on how that measurement was taken it could be deceptive, is there a port for the O2 sensor in that exhaust?
Steve who does ECU tuning for this bike is the absolute expert on the matter, hopefully he will chime in. All I know is that if you have 10% ethanol in your fuel, stoich is lowered from 14.7 to 14.1 (or 14.3 tuners seem to use both) so optimal power occurs at a number lower than 12.8 also
