check the exhaust lobe on the cam. these are prone to wear if oil changes are neglected. try to run it with the airbox lid removed and see if there is any change.

I have a 2006 Sportstman 500HO ATV, EFI. Sometimes it will run 100% correct, other times it will start, idle fine but then when giving it throttle will will start to surge almost like it's hitting a rev limited. Sometimes it will backfire and stall. I already replaced fuel filter, flushed the fuel lines and gave it fresh gas and installed a new spark plug, but no good. I also checked the throttle switch and it's not making contact to stall it. I download the service manaul and tested each sensor and they tested fine which is probablt why I get no check engine light.
This ATV is mainly used to plow snow in my driveway, no salt. It's used around my property but very lightly. It's still as clean as it was when I bought it and it doesn't have but about 40 hours on it.

Polaris seems to have a problem with this issue. I had the same problem with my bike and was able to fix it . I found a bad resetable fuse link located under the front cover. It looks like a plastic case with wires at both ends. cut the case and check the condition of that part. I found it was badly rusted . I removed the part and wired in a 10 amp fuse with a holder. wrapped it up to protect it and the problem was gone. lights worked fine as well as the cluster. Ed.
