This is my first response...so here it goes. I have a 2003 sportsman 600, and YES-it is cold-bloded as hell! I got sick of it killing all of the time in winter, so what I did was under the carb, there is an idle screw. I just upped the idle a bit, and it is fine now. Hope this helps you.

thanks for the tip.. when i do that to mine i have trouble getting it in and out of gear, when it finely warms up!! i have to turn it back out.

I had the same problem with mine.There was a service bulletin issued to the dealers for this problem. I waited too long so i had to pay for the work but it is way better now. They rejetted the carb, cost me 130 bucks.
