Re: GK73A coolant


coolant is a bit greasy and greases the waterpump for example..
Its also thicker.
with water the viscosity (right word in english??) will be lower so it "runs" better through the radiatos/hoses etc etc. At the track/races they use demi water with a little bit coolant of bore oil. At my track R1 it cooled about 4 degrees lower when it used water instead of coolant.

But perhaps theres another explanation??

do not use normal water but demi water!!
(thats special water with no calcium in it.)

Re: GK73A coolant


best for cooling is demiwater with a little bit coolant.
But....when my R1 engine was blown i splitted it and had to drain the cooling system. I always drove with demiwater but there still was any rust in it....
So i changed the demiwater for coolant and raced with coolant only. And the rules from the racecompetition....!@#$ it emoticon

picture of my fastest bike ever.
 Lot of YEC tuning parts on it...freakin animal it was!
