If the engine isn't knocking - you're good to go. Higher octane gas may not make it burn better, run smoother, get better mileage. You're just burning up cash. If you hear the engine knocking or pinging, then this gas is not the right kind for your motorcycle.

Gas Myth - that higher octane fuel leads to better performance. Most newer motorcycles have computers that prevent knock and pinging by constantly adjusting the timing of ignition. Sometimes premium is more inferior fuel than regular. High octane resists knock because it's harder to ignite than lower-octane fuels. Some engines start more quickly, and run smoother regular, even though the manual says to run high test.

Higher octane does not out perform regular octane in preventing engine deposits from forming, in removing them, or in cleaning your engine.
