guys, I am new to the forum and thought I would try to explain what was happening to my 08 sportsman 500 H.O. to see if anyone has had this happen or might know what is causing the problem. I bought the machine new and for the most part, it runs great. However, during the summer months when it is hot, after a long ride it will start to backfire, sputter or miss, and when you let off of the throttle it will go dead. It will not start again until it has completely cooled off. The fan is working fine, no warning lights or anything. Any help would be appreciated. Thanks!
