Take off the front bumper so you can get to the radiator real close. This is so easy once you start taking off the bolts. It takes me about 3 minutes to have it off. Spray some degreaser in the radiator and let set for a few minutes. Then hose it off. It will eliminate your problems. I got to where I do it after each time after I get home when I play in the mud.
Exactly. My friend had overheating issues at Mudfest this weekend and the cause was ofcourse a clogged radiator. If your in mud at all, even a little, it can cause cooling issues. And I bet that 700 is water cooled so it's very dependent on that radiator.
