i just did up my 700 rmk porting pipes shaved the head .....but now i can't keep the exhaust temp down bellow 1300 degres !
i bought some 110 octane race gas at 3.00 a liter and would like to know how much to mix in to bring the temps down .how many liters per 100 degrees?

That is way to hot!!!! The sweet spot for 700 polaris engines is 1100 degrees give or take. try adjusting you air screw in a lil bit on each carb, that will make it run richer. DO that befor the high octane fuel. That is why i haven't done that to my 700 rmk, because of the heat issue, but yeah, dork with your air screw first.
