I have a 2006 sportsman 450 with 1200 miles have had it for 4 years and last spring (2015) it started acting up. once its warm you sometimes have to feather the throttle several times to get it to going otherwise it will just start to studder and not go anywhere. Also doesn’t like hills will studder going up hill and the only way to get it to go is to stop let it idle for a minute. Then it will go about a hundred feet and studdering again.

I am getting very frustrated with it. I’ve have had it to two dealer about six different times and spent over $1500 trying to figure it out with little improvement. About ready to part it out and buy a different brand atv.
