Does anyone run this fluid in the 650 and is it worth while getting it.I am new to the atv forums but i am loving them. The fan on my kawi seems to run all the time no matter how warm or cold it is out side and i live in Northern alberta and believe me it gets cold here!I run 27" outlaws on the bike and i am thinking that would make a differnce with the fan running all the time.I just wanted to thank nyroc as well and his tech tips for the info on changing the red and black spring I did it myself and it was way to easy ,thanks nyroc!
