Wrong Wrong Wrong........
The ZX14 and Busa's make more power on 87--89 octane on Jerry's dyno........All higher octane does is slow your timing down,, ignition. Unless a guy has high compression etc and needs to slow the timing down--burn rate you will make more power with lower octane fuel. It ignites faster and will get your engine burning the fuel a little quicker. More octane on a stock bike will not give more power unless it is needed---your bike pings with the lower octane. My roadstar has patrick racing pistons, cams etc.........I have to run 93 octane in it. Wish I did not have to but it will ping with out 93. High octane on a stock vehicle is a waste of money..............Unless it is required. If your engine spark knocks you had better bump up the octane. Mine runs great on 87--89 octane. Most newer vehicles now with computors will since the higher octane our lower and change how the engine runs with it...............again no more power.............In the old days with just a carburator and no computor the octane either way would change how the engine ran...........All you are doing today unless needed is wasting money on high octane fuel.
