1997 Polaris Sportsman started bogging all of a sudden

Recommended Posts

I have a 1997 Polaris Sportsman 500 4x4 that recently started bogging. Was riding down a road and all of a sudden started bogging. I tore the carburetor off, cleaned the jets , checked if there was spark. I'm pretty much out of ideas. After cleaning the carburetor, put it back on an now it wont start. Any ideas?

Is there gas flowing into the carb? It doesn't have to be gas related either, you could have an ignition/coil/plug issue. Test the plug for spark.

Check if it is a fuel issue by pouring a capful of gas down the sparkplug and see if it will start.  If it does, it is a fuel supply issue. Check carb again (99% of the time in these situations the pilot jet is plugged).  Then fuel filter?  Fill gas tank. lol

I just got a 94 Polaris sportsman 400 4x4 that has been sitting for awhile I cleaned the carb got it to start and run but I feel like its over heating I know nothing about the cooling systems on these also I notice the voltage regulator gets extremely hot while its idling none of the electronics work on it no lights of anykind head lights nor dash lights I jumped it to get it started also when I got it started it wouldn't go into reverse other then that it looks like a really nice bike no damage what so ever so I imagine with a little work this will make me a nice bike any suggestions would be greatly appreciated thanks.

      Can't figure out whats wrong, battery good, charging fine but speedometer needle flashing. I know my fuel sending unit is not working but atv was working well last year. Now it was blowing fuses. I did engine code check but none there. Gas gauge flashes and shows FUEL in capital letters. Need help as just cannot figure this out,
      I might pull the fuel pump out and put new float as likely saturated. Don't know if that would give me all these problems ??
      thanks

      Hello I am new to this site and I havea problem. I have a 1987 big bear 4x4 that will not spark. I tested pick up coil per repair manual and I tested my new coil both ok. It puts out 9 volts at the coil but It is reversed polarity. So when I hook my meter up to it she shows -9 volts while cranking. When I put a test light  on it it flashes. Being an electric system this should tell me something but I don't know what its telling me. I have yet to meet one i could not fix but this old girl has me stumped. Any help would be awesome. Thanks to all.

      1997 Yamaha 350 Warrior, should there be oil in the stator area? Have a no spark situation.

      Have a 2001 polaris sportsman 500 4x4 atv and when I put coolant in the radiator it starts leaking from the exhaust. The valves are sealed but it stopped making compression. Do I need to just replace the head? I just rebuilt the hole top end and this is the only thing +valves that I have not replaced and was wondering if that is why it's not starting up. Need answers please.

      Hey guys I'm new here. I have a 88 warrior that has intermittent spark. When I got the bike the guy said it needed a stator.  So I tested the stator and the Source coil has .310,  Trigger coil has .363 an .367,  Alternator side has .05 to .06 on the three. Which all seem in range. I did find that the ignition coil was bad and replaced it. After I  put the new coil on i got spark but only now and then. The bike won't spark while I'm holding the start button,  but as soon as I let off it will spark sometimes. I ended up unplugging the voltage regulator and it will spark every time I let off the start button, but still will not spark while I'm  holding it. What could this be?

      Hey just picked up another scrambler 850 was told the tps was bad.  This atv has been beet to hell.  Wiring has been tinkered with the crankcase has been replaced recently and the motor rebuilt (can see horizontal scores thru spark plug hole where it’s just been honed out and rebuilt)
      my guess is it was ragged out till the motor blew a rod and rebuilt but the clown that did it couldn’t get it to run again and sold it.  When I bought it it would pulse and smoke black at idle and die with throttle.
      New tps installed and it won’t run period.  I went to celebrate it and I’m getting 5 volts on 2 of the 3 wires running to the tps.  Is this normal and if so how should I celebrate it?

      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.
