What causes a Polaris Sportsman 500 to stop accelerating?
Usually, a dirty air filter or carburetor, stuck-on-close choke, plugged main jet, junk-filled float bowl, misadjusted valves, or air intake tube blockage is responsible for this restriction. Resolving any of these causes will vary depending on the year of your Polaris Sportsman 500.
What to do if your Polaris has HIGH idle?
Thanks guy for the advice! If you are running an open air filter you definetly need to get that air/fuel screw cap off and adjust it. You should porbably get a bigger pilot jet as well. I ran a 50 pilot on the stock carb with an open air filter and it ran great.
Why does my Polaris ATV idle but die with throttle?
I pulled my fuel line to the carb and started it, when I gave it throttle it pumped more gas so I know it has gas to the carb. It seemed to run the same with the line pulled, until the remaining gas in the carb ran out. That makes me think it’s a fuel issue with the carb.
What was the problem with the cams on the Polaris 500?
The cams in the 425s and 500s of that era had a problem with the oil journals in them. The result was excessive wear to the lobes. I have replaced many of these cams, and the new design has extra oil journals and they are larger.

Can a Polaris Sportsman be used as an ATV?
Apparently it is common on the older Polaris atv’s, especially the Sportsman/Xplorer 500. More expensive than I was hoping for, but at least it can be used now.
How long does a Polaris ATV run before it dies?
It runs about 10 minutes, dies. The really weird part is that if you let it sit about 5 minutes it starts right back up again and runs great again. That is until it dies again.
