Premium fuel is easier on the components of the engine? Based on what evidence? Where does something like that come from?
It's almost impossible to get people to give up their bias that premium fuel is "better" than regular fuel. Premium fuel is only different from regular in having additives to slow down the combustion process to prevent pre-ignition or pre-detonation in a high compression engine, which the GZ is not. It actually has less power or energy in it per cc. or oz. of fuel compared to regular, gives worse performance, gets worse gas mileage, and is more expensive. The GZ engine was designed to use regular fuel, period- you want to use premium, for whatever reason, go for it, it's your bike, your pocketbook. Do a little research on numerous threads on this and other forums and on the web about what exactly high octane fuel is and you'll be quite surprised.
