swrbansheeboy Posted April 4, 2009 Report Share Posted April 4, 2009 110 will keep even a stock motor running cooler than pump gas. i agree but i also think it runs cooler because by running a higher octain fuel your effectively retarding your timing (in the sense of when the fuel ignites). when you advance your timing mechanicly your engine has a higher tendancy for pre-ignition so to counter-act that you run a higher octain fuel because it ignites at a higher temp correct? when you run a higher octain fuel in a stock bike doesnt it cause ignition to occure later than it normaly would with say premium? this is just the way i've always understood it so any additional insight is appreciated as i know you have alot more experiance than i do, i'm always open to another take on the subject.
