Running it on anything above that will not improve performance (very common ricer fallacy). There is the possibility that it will run smoother as you noted due to additives in the better quality fuels. 2002 Sporty , Ironman 2.5" spring, 2" body, 15 x 7 ROH wheels, K&N, 15 x 10.5 Simex Centipedes, Powerchip 91.

More effect can be had by adjusting driving style and tire pressures. Bang-for-buck the net effect is it will cost you money to run high octane fuel over and above any savings you may make in fuel consumption. 2002 Sporty , Ironman 2.5" spring, 2" body, 15 x 7 ROH wheels, K&N, 15 x 10.5 Simex Centipedes, Powerchip 91.
