2006 Polaris Sportman 500 4x4 EFI Engine Stalls


Recommended Posts

i have a 06 sportsman 500x2 efi that did the same thing several times .. an the dealer said that the throttle cable needed 2 be adjusted slightly to take care of it ... they said that it would do it more in cold weather and be more noticable in the cold ... they said i could adjust the cable a little or adjust the throttle position senser slightly 2 take care of it ... i dont remember what they said to set the idle at but you should be able to find that out from the dealer or from your owners manual or a service manual... i would also run some injector cleaner and some good hi octain fuel throught it ...

it can be moved slightly on the bolts that mount it ... but you will have to have the dash on the tach setting and adjust it to set the idle speed to the factory setting to get it to idle properly... the tps has a spring in it that gets weak with use and can cause the problem ... it can be adjusted to take up the slack from the spring being worn.. but the tps will need replaced eventually .... you can also adjust the throttle cable to take up the slack also.... the vibrations that an atv experience are usually worse than an automobile and will cause the tps sensor to become out of adjustmen easyer than 1 on a car... and will cause the problem of it dieing like you are having ...

      Hi everyone. 
      Let me explain the thread title. 
      My husband and I are very active in the nudist community, and we have stayed at many and most of the mainstream nudist and clothing optional campgrounds in the USA. We are now approaching our retirement and would like to start a podcast to share those off the road / backwoods / little known camping areas where nudity is allowed. We have purchased a 5th wheel camping trailer with a rear garage for the ATV and now need some good reports on the one to buy. 
      We are most interested in a side by side unit but would love to get your thoughts. 
      Feel free to stop by and say Hi and ask anything you would like to better understand what we are looking for in an offroad unit. 
      Thanks for reading and hope to hear from you.

      I'm assuming, it's alright to test the engine after adjusting valves without the rear axle installed? Can someone please verify this? I'm waiting on axle parts and wanting to get that done while waiting. Thanks! 🙂

      Hello folks, my machine wound up with I think water in the tank etc. It runs but speeds up and slows back down randomly. When not running I don't see gas dripping  from the drain nipple on bottom of float bowl and drain screw is closed tight. With normal idle speed I see no leaking. When the idle speed increases quite a bit on it's own, gas appears to start slowly dripping from float bowl drain nipple? I'm wondering if the carb is flooding and the gas is actually coming from higher up and just appears, to be coming out of nipple but, is actually running down the sides of the nipple? I put a kit in the factory Mikuni carb last year after sitting for a while and I think the gas in the jug I used had drawn moisture. I plan to pull the carb tomorrow and clean everything out. I was just curious if anyone else thinks it's probably something in the carb and is, acutally a flooding problem? Thanks Folks! 🙂

      Hello All
      I have a 1987 Suzuki dual range 230 and a 96 bayou 220. I'm trying to figure what oil to use. I normally put Amzoil synthetic in most everything. But I understand there are concerns over the wet clutch. I've heard rotella 10w40 full synthetic,5w40 synthetic,10w30&40 non synthetic. I do live in Michigan, so temps cold and hot are encountered. It could be below zero or 90 degrees farenhight. I don't have manuals for them. Any help is greatly appreciated!

      I have been rebuilding some ATVs in my spare time and teaching myself along with the help from the internet how an engine works and getting bikes running again is quite enjoyable. I even built an arctic cat 300 4x4 from two parts bikes the had seized motors and missing parts. It was pretty enjoyable. 
       
      So I am now working on a sazuki quadrunner 300 1992 which had a whole list of issues when I got it. I have fixed almost everything I need to in order to get this bike running. But something is going on inside the head or crankcase. 
      I had to replace the timing chain because it was very stretched due to the previous owner.
       
      What the issue was, the timing chain was off the sprocket inside the engine due to it being stretched it slipped off. So the previous owner rebuilt the top end thinking it would fix it which it may have temporarily, but when doing so they welded an extra inch onto the tensioner to hold the chain tight. Which as you can imagine caused a dozen other issues.
      So that stretched the chain to the point where I could remove the cam with the tensioner in.
      It beat the sliders all to hell. Destroyed the cylinder housing and obviously ruined the tensioner. 
      I didn't realise all of this until after I rebuilt the engine.  I noticed wear where the timing chain runs through the cylinder. I found the cam had no retaining chair, or clip whatever you want to call it so the cam was beat to sh** also. It had almost an inch of play side to side.
      So I pulled the head off of my parts bike and fixed all of it. Then put it together and went to pull it over and found it was not on the sprocket (this is when I realised that all that damage and the welded tensioner was because the timing chain had been off the sprocket) 
      So I pulled the stator cover off and pulled the flywheel (which I should add to get at the stator cover I have to remove the rear tire and a arm as well as remove the bolt through the front of the engine. And the exhaust system has to be removed to pull the cylinder as the exhaust guard is bolted to the side of the timing chain tensioner. Stupid setup. Glad the king quad doesn't have that. 
      So I got everything apart and the flywheel off. New timing chain (nice and tight now) put the head back together and flywheel but it is quite hard to turn the engine over. I can but with difficulty. When the valve cover was off it seemed to spin much more freely. Before I tear everything back apart and start again any ideas on what it is?
