[QUOTE="Wingman, post: 285214, member: 4328"] Even though the thermostat holds the minimum engine temp more or less constant, the excess heat has to go somewhere. In this case the excess heat is sent to the radiator, passed to the air flowing over the radiator, then blasted onto the rider. :angry2: I have no idea if combustion temp would decrease significantly by using higher octane ratings. However, adding (or reducing) fuel does indeed decrease combustion temps. If you decrease the amount of heat produced, you will also decrease the amount of heat that the radiator must pass to the air. To get this reduction in temp by adding fuel, you sacrifice some power (and generally a drop in mpg) in the process. I'm sure it is not nearly as noticable as some other things that could be done to reduce heat (removing the cats or improving cooling airflow for instance), but every little bit counts when it's your chesnuts roasting by the proverbial fire.
