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 was reading another forum recently about fuel leaks and possibility of fire happening. Reminded me of an incident I had a few years ago while working at a Can Am dealership. The quad was a stolen & recovered Outlander 650 that had been tampered with. These quads have an electronic safety system, similar to their DESS system on the sleds. You cannot bypass the key switch and get spark without a computer with factory software. Anyway, I was trying to determine what was damaged since the thief had attempted to hot wire various electronic parts. I got all the extra wires removed and things looked back to stock. Pulled the spark plugs and was going to check for ignition and if the starter still worked. Well, they both worked alright and guess what - the cylinder was flooded with fuel! Instant flames with gas spraying all over...great!! I managed to use my hands to put out the fire, good thing I had on gloves (but choked they were ruined of course, haha). Seems it's possible to flood an engine with efi when you put power straight to the injectors, doh! As in much of life, you cannot take things for granted (I'd only seen carbs flood like that). And even though it had spark, the quad still needed a new ECM to run - that part alone was $1200. So lets hear your stories, crazy stuff happens every day I'm sure.

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.

Hi Folks;
Has anybody on here installed a winch on a 2003 Magnum 2x4? I am using a Cycle Country adapter plate (only one I could find), but am having a bit of trouble getting it all to fit properly, and am looking for someone that may have done this install and/or may have some pics of the installation.
Thanks!
Eric

I am having an issue where it sounds like the gears are slipping if I hit the throttle really hard and also after letting off when the engine brake is applied. Also, the drive train that goes to the front also rides again the gear shift box. I will attach pictures and a video here shortly.
Thanks in advance!

Trying to change front wheel bearings. I removed the cotter pin and castle nut. Hub won't budge. Is there an additional retaining clip? Seems to be one of those push on type that barbs on the thread of the spindle. How do I remove it?
