2001 polaris sportsman 90 will not shut down

Recommended Posts



Guest

If memory serves,there should be a black wire with a white stripe coming out of the CDI box. It may turn into solid black. This is the ignition kill circuit. When you turn on the key switch,handlebar switch to run and the safety tether is in place, this wire is grounded. In other words the wire must be grounded in order for the machine to run. When you turn the key switch off or the tether is pulled off, this circuit is opened,thus shutting down the engine. Since yours won't turn off i'd be suspect of that circuit be grounded all the time for some reason. Either a pinched wire,bad switches or somebody has been in there. A quick test would be to disconnect the black w/white stripe wire at the CDI box and see if the motor dies or if it quits sparking. Then all you have to do is check the circuit and find the fault.

      My 2014 750 king quad stalls sometimes when I touch or turn the handlebars,the problem has gotten worse,my machine has 475 miles and is only trail ridden,I have a new factory battery and i have 14.2 volts when the quad is running and 13.3 on the battery when not running,also using a multimeter there is no change in volts when turning the bars until it does stall,If I pull the 40 amp power steering fuse it will not stall.......I've been told its the ECU,Hate to buy one if thats not the problem,but its kinda leaning towards that,,,,,need some opinions.

      So i have an old yamaha bear tracker that was given to me from an old farmer I know. I decided to refurbished it and fix all the quick fixes on it. I am pretty sure that it is either a 1999 or 2000 based upon the original wiring harness. Little did i know when I bought a new to me wiring harness from ebay that it was from a 2003 or 2004. My question to everyone is do I need to have all the stop switch assemblies hooked up? I think there are three on the 03/04 models and only one on the 1999 to 2000. Any help I can get for this would be great. I haven't run it yet due to the motor and crankcase is in two totes.

      Anyone know what the fuse terminal marked UNSWITCH  does  .  Even with the key off it is causing a drain on my battery and I'm trying to figure out  what that terminal goes to.  It's a 10 amp fuse. If I pull it the "short" goes away.  Thanks in advance.

      Had a spark-plug break off, had to pull the head to get it extracted. Where the heck is the timing mark on the crank? Do I need to pull the stator or flywheel to find it? When I pulled the head I had the mark on the cam lined up pretty good but I cant remember if it was perfect and don't want to reassemble a tooth off and have to go back through the bear of pulling this thing back apart.
      Thanks guys!

      Hi I just got an Polaris sportsman 500 4x4 ATV the other day. I got it real cheap but I started to go into it because it didn't have compression so I bought a new piston and ring kit for it and installed it, but now when I try to start it all it does is shoot fire out the exhaust or the intake of the carburetor. And a timing is top dead center.;I think I can't really tell another way if it is or not. when I put it together I made sure to piston was on top and the cam lobes where facing down where are the cam sprocket is facing up. It has gas and spark. It did start a couple minutes ago but it didn't stay running and now it won't start. Do you think the valve need to be adjusted more to close better?I'm fixing to try that out and if that don't work what is the problem? Also I made sure everything was together good and right and change the oil and changed out the radiator fluid.

      I just rebuilt my 03 sportsman 400. Put everything back together added oil per the manual. Pinched off the oil tank vent line 2" away ran for 45 seconds then cut it off. Check oil level and it was still way high so I wasn't confident that it primed so I did it again. Checked again and it's the same. Remove the oil filter and it is dry. I did the procedure again and the same results.

      I'm worried to keep trying this as the only oil in the engine is what I used to lubricate the parts when reassembling the piston. The crankcase was drained as well.
      I Removed the oil tank and checked all the lines for obstructions and the screen filter and the vent hose and everything is clear. I even pulled a small vacuum on the oil tank while it was pulled off to make sure there were no leaks. The dipstick cap was on tight so I'm not sure why this thing is not priming.

      Anyone have any suggestions. I thought about pre-priming the oil lines from the oil tank to the crankcase to hopefully help the system prime. I'd like to be able to add some oil to the crankcase to so I wouldn't feel so bad about running the engine for another 60 seconds without oil. I dropped just a little bit of oil in the spark plug hole to help condition the sleeve right now.

      What do I do? Anyone had or heard of an oil pump failure on these. Btw oil pump is working fine before I did the top-end rebuild and the oil pump was not touched.

      Please help!!! Thanks all for any and all help.

      Hi im new to the site. I have a 99 sportsman 500. I has been sitting for about a year now. I bought a new battery for it the other day and now i dont have any power to anything but the winch. Any help would be great. I already cut the pouch and checked voltage on both sides of the circuit breaker.
