I have a 2010 Sportsman 550 XP that this winter started giving me problems starting when the engine is cold. It seems that the only way to get it running it to give it about 3/4 throttle. Sometimes it will backfire when I'm trying to get it started. After it starts, it will run rough and not idle for about 30 seconds to a minute until it warms up a bit. It seems the warmer it is outside the easier it is to start. It is acting like the computer is not adjusting the fuel air mixture (like applying a choke on a carb). I have tried disconnecting the battery for about 5 minutes to see if that would reset the computer but that didn't work. Note, after it is warmed up it runs like a champ. No problems at all. It is just having issues cold starting. Any help would be great. Otherwise my searches have mostly turned up empty.
Thanks
