  1. Polaris Sportsman
    Hello everyone. I’m new to this forum and thanks for any help in advance. My 2006 sportsman 450 battery will not stay charged. There are also other little “gremlins”. Sometimes when I hit the throttle, the engine dies (when cold). The taillights will turn on and off when I hit throttle. I...
  2. Polaris Scrambler
    Hi guys. Just bought a 2000 scrambler. It had overheating issues so I replaced thermostat, checked water pump( all good), and replaced radiator and cap. Took it out for a ride and everything was running awesome! Got to around 20 miles and my radiator blew up. Come to find out the top plastic...

    I have a 2016 sportsman 570 that will bog down and die once the engine gets hot. Will not restart until it cools down. No check engine or error code. Once cool, acts normal for a bit. Winter months, not an issue. Cooler summer days, I'm able to go 20+ miles. Hot summer day, I'm lucky to get 10...

    My neighbor recently gave me the job of figuring out what was wrong with their ATV (2003 Polaris ATP 500 H.O. AWD) There are multiple issues, but it is still driveable. The first problem is overheating. The fan does still work perfectly, but even under no load at low speeds, it will still say...

    I have a 2004.5 sportsman 400 that keeps overheating on trail rides. It is full of fluid and the system has been burped.

  11. Polaris Sportsman 570
    I recently bought this bike 2 months ago, and have fell in love with it. I've already replaced the front right axle on it (my own fault for where I was going), but otherwise have had no problems with it. Recently, after riding for about 2-3 minutes the Over Temperature light will come on, the...
