Hey I have a problem with my wide track and I am wondering if anyone has run into this same situation. this machine started overheating big time. I used it most of 2010 in 14 to 20 degree weather and had no issues. this last winter 2011 in March The weather was about 10 degrees warmer and I had nothing but trouble. I could not even pull an empty sled behid me. This machine did this over and over. I even ran it ontop of ice in about two inches of overflow and it still over heated. I was finally able to get it back to the dealer. (my place is about 95 miles back in the bush with no roades) The dealer wasn't sure what the problem was, first they said it was because I scarred the radiator with screws (which of course it ran all last winter with them in, only on the side of the track) and now after they are saying they think it was the brain. The thing is, this machine is no longer being offered in a 800 due to al the overheating problems. So I am just wondering if I am the only Alaskan who has had this problem? If any one has had this situation please let me know. I'm not sure if the new brain will really fix the problem and out in the middle of no where is not a great place to find out!
