Hi, I am having problems with my 2004 sportsman 600 stalling. I have changed all the filters, the plugs, oil......it idles at 1150-1200 RPM's is very smooth while idling, but for no apparent reason while I am riding it & I slow down it quits. It does start right back up, but I would like to know what is going on & how to fix it. Has anyone out there had a similar problem, if so what did you do to fix it. Thanks.
