I will continue riding with regular unleaded of at least 86 octane as I have with this bike and five previous Honda GLs.

Mother Honda designed and built a marvelous machine in the F6B! They continuously apply the KISS Method to their Engine Technology (except for changing the air filter)! They provide the initial 36k warranty and recommend 86/87 Octane fuel! Why folks insist they know more than the manufacturer has always puzzled me! If you feel higher octane is necessary for "your machine" then go for it! I personally prefer to stop at just about any "high volume gas station" fill my tank and ride on! Life is too short to split hairs on octane
