Octane boost will result in a zero increase in power. The octane rating of fuel is the number given to tell its resistance to detonation. Gasoline of all octane ratings have the same heat content when burned. If you want to pour in some hp try nutec special 4, but your bike has to be tuned for it. It has nasty additives that do actually add more hp, and it smells like it too. At $15/gal it is probably cheaper to have the normal go fast things done to the motor. Avgas uses lead for its anti-knock properties, but it still won't get you more power.
