2010 polaris Ranger Pursuit 400 HO running rough

Recommended Posts

Neighbor dropped off his 2010 Ranger 400 HO. Said it was missing and backfiring. I replaced the plug as it was carboned up (kids use the side x side for chores and it is only idled around yard) Unit ran great, sent back home and it ran great for about 5 hours of run time and then it wouldn't start. He brought it back and I changed the plug again and it would start but would not run great. Pull plug and it was really wet. I suspect the carb needs cleaning and that is the direction I plan on going unless someone else knows anything about these units. ( I have never worked on one of these).

If you know of something else I should check let me know.

Also I am looking for a service manual for this unit.

Thanks

PKR

I would go right to the intake and check there first.   My guess would be something is in there or the air filter is breaking apart and small portions are getting sucked into the carb?  Air filters after a while break apart if they are not kept oiled.   Simple stuff first, after that get into the carburetor etc.  

Check for bad fuel, water in the fuel, poor fuel flow. Maybe a bad petcock or screen, all this stuff happens.

Thanks for the reply. I had taken a gas sample from the tank yesterday and it looks good today, no sign of water.

The air filter and everything else looks good. My plan today was to pull the carb but I decided to try to start it first. It fired right up and purred like a pussy cat. I ran it around the yard for about half an hour and it didn't miss a beat. I'm not to sure what is going on. I'm starting to wonder if the kids are flooding it when they try to start it and sitting out in the cold it isn't clearing itself???

The only difference between it being at the neighbours and being at my place is it is left outside there and is inside my shop here.

I'm going to move it outside tomorrow and let it sit for the day to see what happens.

Could be moisture getting into certain electrical components if its left outside  or just like you said, the kids flooded it.  Give everything a once over and make sure all plugs are good etc.  maybe run some high test fuel and monitor the machine for a bit.

      recently picked up some project bikes off CL for cheap.  got a honda fourtrax (the ancient 4x4 kind with the straight axle in the front as well as the rear and a back-up kick-start)  plastics are crap, but my goal is to get running like a champ and patch the plastics up and sell to one of my many friends that want a reliable 4x4 for dirt cheap and doesnt care what it looks like.
      so the former owner says it needs carb rebuilt, but its sat for 3+ years since so who knows.  things I see:  carb is missing (he gave me a box of parts along with the bike), engine turns over and feels good with kick-start, brakes need work, battery missing (That always puts me off, cause then I know most likely someone's been tampering with the electrical.

      I posted earlier looking for a wiring diagram, but maybe someone can help me with the problem if they’ve had it before. 
       
      The quad Will start and idle ok, when I open the throttle it will rev all the way up until WOT and then it dies back down to idle, and if I keep the throttle wide open it will rev back up. It will do this over and over and over. 
       
      I replaced the carb, (twice), Rectifier, battery, and spark plug.  The Stator ohmed out to the proper specs from dinli.  The other issue i can see is I’m not getting 12v on the choke circuit. The lights don’t work either. 
       
      possible bad key switch? Maybe the new rectifier is bad? All the contacts on the key switch also ohm out properly    
      comprsssion is up to 125 psi and spark is there. 
       
      Reed valves look great.....
       
      im at a loss. Any trouble shooting advice would be appreciated.

      I am working on a Honda sportrax I just got my daughter for get birthday and the reverse and neutral light are not working. When I traced the wire down I saw that it wasn't plugged in but I don't see where it is supposed to connect. Does any one have a general idea of where I should look?

      Just bought 06 KingQuad 700 and first ride out hit a mud hole, not to deep and it shut off and would not start. 
      Got it home and found the spark plug hole was full of mud and water. Went and bout a new spark plug and began cleaning it out. Put a deep socket in there and it wouldn’t grab. Took a pic with my flash and this is what I see. Any suggestions? And what is it??
       
      previous owner said it had a new coil so that’s why I decided to change out the spark plug, also ordered new coil should be here by the weekend.
