Polaris 500 sportsman give it gas stalls


Recommended Posts

I just put in a brand new cam and a brand new cap and it just did the same exact thing is there something that holds that cam or decompression ring in place. Also I noticed another thing when I started it disconnected the battery ran like it was supposed to hook battery back up couldn't hit the gas again. I'm getting so frustrated with thing its unreal about the hundredth time I've taken it apart.

It will go in 2 different ways but I put it in exactly how the service manual showed it both times now before I put it in and wounded the spring once never had this problem now manual says put it in with spring in relaxed position do not wind it once it will not work right but both times broke the case out like something is throwing it out the busting the weight off and weird thing it started running perfectly when I unhooked the battery its getting so much juice from stator it blew my neutral light out this is crazy I just keep throwing money at it and just keeps costing me more its insane

I went and got a new cam yesterday it doesn't even come with the spring preloaded which sucks. Right now I'm trying to find a cap before I can try it again. Just worried to break another one 

Also ? How on earth can the motor go backwards some where on hear someone said sounds like the motor went backwards how can that happen

That can happen if the engine backfires. Usually if timing is off or an unusual amount of fuel that builds up in the cylinder.   The engine kicks back.  

Can you screen shot the page that explains the cam and spring installation and post it here ? I want to read it. I don’t have time to start looking for the manual

      Hi, I am having issues with my TRX350D fuel pump.  It suddenly stopped running so I have replaced all the fuses and cleaned all the terminals.  I have fitted a new pump, fuel cut-off relay and rectifier.  Still nothing!!  The pump runs when attached to a battery.  The engine will start on the choke and the filter fills with fuel but it will  not rev and dies when the choke is closed. I have power to the relay but nothing at the pump black/white wire when cranking the engine.  Any ideas where to go from here would be very much appreciated!!

      Hi guys. I have a problem where the quad will start and run well for about 5 minutes and then it dies. On inspection the airbox has oil in it (quite a lot). The oil is pumping through the cylinder head breather hose. This problem first happened suddenly. I have since done the top end including, piston, gaskets, rings and valves. I have also done the carb (not that I thought that this was the problem). The compression seems normal. The only thing that I can think of, is that I did not grind the valves well enough. Anyone experienced this? If so, how did you fix it? Any other thoughts?

      I have been exploring all the options available, so many, its hard to choose. I have kind of narrowed it down to the Honda Pilot, Subaru Outback, and Kind of looking at the Outlander, although its a little small,  the new one is nice looking. Just wondering if anyone has any recommendations or gripes with any of these rides. I have driven Jeeps for the past 25  years and they have been great, but their price point has gotten to high. Expieriences good or bad would be helpful. Thanks!

      Hello everyone, I just picked up an 02 LT-F250F the other day and have been in the process of tearing it down to fix some stuff- one of which was the cylinder base gasket leaking like a sieve. Well, I know why that is now, and I also discovered that someone had been in there before. I didn't take pictures, but it looks like it was probably run low on oil at some point, the cam journals and the "bearings" (for lack of a better term) in the head and the valve cover are totally wiped out, very deep grooves.  From what I know it's very difficult to repair aluminum in this way, so I'm trying to figure out where to go next.
       
      1. Have someone grind down the head and valve cover and fit actual bearings in since the aluminum is screwed, and have the cam ground down to match.  I have no idea what this would cost.
      2. Buy a replacement head+cam+valve cover.
       
      #1 I was hoping someone might have some advice on, but #2 seems like it'll (probably) be the more cost effective option.  However I'm running into some difficulty, it seems like the 2001 and 2002 models specifically use a different head part number,  11100-19B10, instead of  11100-19B01 like for all earlier models.  What exactly is the difference between them? There are obviously far more of the earlier heads because it ran for over 10 years.  Are they actually interchangeable? I've also noticed there are heads from the LT250EF that has 4 valve heads but also otherwise look identical.  Would those work as well possibly?  I'd like to not have to drop $500 on machine work or new heads on a $1300 quad that I'm already putting a bunch of new parts on.  Oh, and it has a new piston and the cylinder itself looks pretty good too, as I said someone was in here before me.
       
      Any help or advice would be greatly appreciated. I'll post pics of the carnage tomorrow.
