"10. Finally, for the sake of "cooler running," premium fuel is promoted by some on the Internet. Anyone who has worked around Hondas, or for that matter any of the Big Four brands, for any length of time, knows that their standard road models have always been designed to run on unleaded 87 octane for so long that this fact should be included in the Smithsonian! A Honda bulletin about this exists dated 1971, so we have to look at least that far back. Premium fuel is a bad idea on bikes not specifically designed for it (such as Honda's own Turbo and any number of current hyperbikes, not to mention four-stroke motocrossers). Premium carbons up the valves prematurely and is the cause of some of the top end work that needs to be done on Gold Wings, especially, as well as other Hondas."

So running prem is not a thing recomened? Rut ro
