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.

      Just now rolling over 100k miles. Been feeling some steering weirdness so I get one front wheel up in the air and push at 3 and 9 and sure enough there's some wobble. Pushing at 12 and 6 gives no play at all.
      Although I'll probably be replacing the worn part myself I need some help diagnosing what all might need to be replaced. And since I need an alignment anyway I've made a deal w/ my local Goodyear tire shop to do a pre alignment inspection and identify my bad part(s) so I can replace them before they do the job.
      When I drop the car off what specific parts should I ask them to look at? I'm sure tie rod ends but what other kind of worn parts could be causing movement on the 3-9 push test?

      posted a while back - it was running at one point - I have all the plastic shroud off - it's down to frame and engine now
      -fuel pump: when line from petcock is attached, no fuel comes out other side to carb; the line to the carb is open (can blow through it); I thought when I cranked engine that the pump would spit out fuel on other side but it does not; I removed fuel pump and opened it up - diaphragm looks good - but internal areas had lotsa calcification build up - I cleaned this out and dried it good - the clear plastic pieces (?diaphragms) aren't broken - the spring w/ steel ball on end moves freely; am putting it back on tomorrow; but can anyone answer about the pump? isn't it supposed to pump fuel through it... to other side... to carb? puzzling
      -along with fuel pump: I replaced petcock 3 weeks ago (gas tank had rusty fuel in bottom - cleaned it out prior to new petcock); when I turn petcock arrow NOT to on or reserve, fuel comes out of line; when I turn it to on or reserve, fuel doesn't come out; puzzling
      -I don't know what's on back of fuel pump - it's a valve that has a hose coming out of it - looks like it goes to engine/carb - I haven't traced this out yet - what is it?
      -can squirt gas on air filter and engine will run for 2-3 seconds then stop - fuel in top of carb (under diaphragm) does same
      -it likely needs carb rebuild - will get to this - but something isn't allowing fuel to get from fuel pump to carb
      -I THINK it has a mikuni model x carb - diaphragm is ID 26mm  OD 68mm - hard to find inexpensive diaphragm, I guess because it's a model x
      -last thing - I replaced solenoid due to old one clicking; I HAVE to be charging the battery or it won't start/turn over - battery just goes dead; but if charging, it'll turn over nicely; i'm guessing it's a bad battery
      -any help appreciated - I've never owned an ATV before - inherited this beast from grandparent in-law

      Hi,
      Oddly I'm having  a hard time ordering front brake shoes for my '98. 
      I'd appreciate recommendations on decent, widely available shoes if possible. Ideally available in Canada on short notice.
       
      Thanks much,

      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.
