running cooler

[400xrider]

I have a brand new 04 400ex. Will running half 93 octane and half racing racing help it run cooler? I heard this works but not sure what you guys think.

on a stock motor, i wouldn't waste money on race fuel. the bike just doesn't need it.

he wants less heat not more power so it's not about a waste of money.

I am not a race gas specialist but I can only say it can't hurt

if its stock then run whats supposed to be run in it.

With it being stock there is really no need to make it run cooler. I think it would be a waste of your money to run race gas in it at 8.00 a gallon, but it is up to you
