Got my Commander about 3 weeks ago and really love the machine, except its overheating. After my 2nd ride LIMP HOME mode was activated. At the time I had no idea what the issue was - this is my first ATV of any kind. I just got the bike and have the 6 month can-am warranty as well as 3 years from the dealer. The service guy told me about the radiator and sure enough...it was FULL of mud. After cleaning everything was just fine. Now its overheating again.....been fine for about a week. Yesterday I cleaned the radiator about as well as I could but the bike is still overheating. No idea what the issue could be. I'm taking it into the dealer tomorrow. He said on the phone he still thinks its the radiator and possibly areas I didn't clean as well as I thought. So my question....if it is the radiator, is this normal? Do I have to be ultra careful about getting mud and dirt on this very expensive MUD and Dirt machine?
