    Polaris Sportsman
    Hi, I have a sportsman 90. When starting cold with choke it is starts and dies unless I give it a little throttle. When started it will die at idle without a little throttle. After I run for 5 to 10 minutes it starts fine and idles will. I inspected the carb recently and cleaned all holes with...

    I have a 2000 Polaris Sportsman 500. A year or so ago we got it running after replacing the kill switch. It ran great but after some use for a couple months it got a flat tire and for some reason we just forgot about it and it sat for some time. Before it sat i replaced the gas cap, fuel...

    Has anybody found an aftermarket controller that works with the 2010 550XP? That idle is crazy high and I'd like to lower it.
  4. 1990 Trail Boss 250 Idle

    Polaris Trail Boss
    My 250 2x4 runs great, but will not idle. In the past, once I drove it for a while it would seem to idle. But now, I can ride for 3 hours and when I stop it will shut off. It doesn't even need gas to stay running, as long as I just barely touch the throttle, it will stay running. I am...

    Midwest
    Hi All, I have a 2008 Polaris Outlaw 525 IRS that I cannot get to idle consistently. I have cleaned the carb really well and have recently replaced the throttle cable. The problem existed before the new cable so I do not suspect that this is the issue. The reading on the TPS sensor through the...

  8. Help with 500 h.o. Engine vibration

    Polaris Sportsman
    Hey forum! I went to go sell my '04 500 and the guy told me that my engine vibrated to much at idle. When I looked closely, it had a slight engine movement, but it's nothing that's ever stood out to me. It's not like a Harley where it's wobbling in there, but you could see slight movement...
  9. won't idle

    ATV Repair and Maintenance
    I just bought a 06 700 Sportsman that was not running. The owner said it was having idling issues and had replaced the fuel pump and replaced the carb. It will start with the choke out but if you put the choke in it will backfire and die. If you let it warm up, you can start it in gear and it...

    Polaris Sportsman
    The float valve went bad on my 2004 Sportsman 500 (carbureted). All of the gas in the tank ended up running into the cylinder and down into crankcase. After replacing float valve, I put a small amount of oil into cylinder. I emptied crankcase and ran 3 oil changes through it immediately...

    ATV Repair and Maintenance
    Hello everyone... New to the forum, but have had this ATV since it was new. The bike sat for a couple years and fell victim to the ethanol in the gas. The throttle valve and shaft were completely locked up and nothing would free them. I bought a replacement carb for it and installed it along...

    Polaris Sportsman
    So when I go to start it, it will start up after letting it sit on the battery charger but I have to have the gas down in order to keep it running. I've messed with the idle control both left and right and neither way seems to hold it at the right rpm's to keep it from dying on me. Also it's...

    Have a 1990 trail boss 250. Recently rebuilt top end. I'm trying to tune the carb now to get it to idle and run properly. First off it requires being pulled over about 7 times with the choke on full and the throttle wide open when it's cold. Then when it's running it will idle fine but I just...
