Stalled out on me twice while riding, first time going down a rough trail in low and slow. Gave it gas, no response, gave it again and stalled. After an hour and a half and many attempts to start, started like nothing happened. Next ride just started going uphill in high and stalled out the same way. Needed a tow home and was finally able to start it with the choke pulled all the way out and giving it gas so I could push in the choke. Runs fine now, but don't trust to ride and shop can't figure out what's wrong. Any ideas?
Have seen this happen to my honda, water gets ingested in the carb when in deep water and settles in the bottom of the fuel bowl. you must remove the fuel bowl drain cap to drain out water
SOURCE: Idling good start good but stalls if pressing throtle
there is a piece of debris floating around in the sediment bowl of your carburetor, its lodged in the high speed jet causing it to stumble and backfire......it will most likely need a carb rebuild average repair cost on this machine is around 150 dollars at a reputable polaris dealer
Testimonial: "thanks I'll clean out the carb and see "

Buy a machine that doesn't have the Polaris name, I own a 700 Sportsman and have had nothing but problems with it, paid 10k for the piece of ****. Thanks Polaris
SOURCE: Polaris 500, starts fine but when you give it gas is stalls
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 2004 700 carb that shut off while riding and then would start up 3-5 minutes later after many nights working on it Ifinally figured it out no help from any dealer. There are 2 circuit breakers under the front rack mine were very rusted, Replaced both never had the problem again. My situation was always only when the lights were on.
Hope this helps

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.
