You may actually lose power if running higher-than-designed octane fuel. This has been dyno-proven endlessly. You'll want to run lowest octane possible that doesn't cause knocking/pinging. These newgen bikes actually has lower-compression than previous pregen engines, and those run just fine on 87-octane.
