So i have a grizzly that started life as a 2002 660 . I have owed this old girl for about a year and a half. Through that time she has started to show her age, and so my project began to surpass her former glory and show up the new model 700’s. I went right for power, making her a 686 with mudbuster cam, clutch kit, jet kit, bigger pilot jet,and opened up the exhaust. Added some gas shocks too. After the planets alighning and lots of trial and error adjusting she was running to perfection with crazy amounts of power. My friends who have 700’s are envious of her. Well everything was going great until this weekend when i went on a trip to maine. It was 90 degrees out and the old girl started overheating every 20 minutes. So i am embarking on a new venture which seems to be uncharted waters, and will be retrofitting a upgraded 700 grizzly 3 cell radiator and fan to her. Has anyone heard of anyone doing this before?
