I agree with jack. 90% will run better on 89 then 110. When I was setting my TL motor up it was dynoed to get the peak power. 110 was the best for only because after adding the V-two kit it bumped the compression of 13.5 to 1. That was a killer bike 116hp stock 5K later it made 136 hp @ the rear. Now R6 was dynoed and it makes its best power on 89 the lead in the 110 fuel with waste the carbs. But that is what I heard from the person that built the motor.GsxrJack said:
