Hey all new member so I'm sorry if this isn't the correct place to post, but I'm having trouble with a 2000 polaris magnum 500 I just acquired. The quad ran when I got it but was having problems that sounded like the camshaft, and sure enough camshaft lobe was pretty much gone, so we replaced the camshaft and exhaust rockers and now the quad doesnt have spark. We had the quad running right before we tore the old camshaft out and now no spark. Anybody else ever have a problem similar? We've been checking for loose wires, checked grounds, and double checked timing but cant get it figured out so any advice would be appreciated! Thanks

I have a 2000 Polaris Xplorer with the 250 two stroke motor
It does not want to start with the electric start, the motor cranks fast, the battery is good, and there is good spark when cranking. The engine starts perfect when using the pull cord, it even starts if I pull the cord slowly and starts with one pull. The engine idles smoothly once started. My wife says she needs the electric start to work.
I started this project a while ago.. I have decided to make one thread I can continuously update..
So , here we go. I got this Raptor 80 in really bad condition.. Rear end frozen, Engine toast, tires dry rotted, tons of rust..etc.. They admitted they beat on it very hard.
Since they do not make these with a drive shaft anymore I decided to restore it from top to bottom..
These are photos of when I got it home.
Next up, the tear down..
First, I needed to tear it down and determine if the rear end was still good... As we all know... That is where it would be cost prohibitive to restore if it is trashed..
Got it completely stripped down and I lucked out... The rear Drum brake was caked solid inside with dried mud. That was causing the rear end to lock up. Took off the rear brakes and the rear end spun perfectly smooth.
Once I got it all stripped apart I needed to take the finish off all the parts. I am going to be powder coating the frame and many parts.. Once the finish is off each part it will need to be sandblasted to white metal .. The guy I use for powder coating gives me a hefty discount if I bring the parts to him ready to go.
You could just sand blast, but that would take a long time to get the finish off. First I used Aircraft Paint Remover.. That stuff is pretty toxic Goggles and Resperator are required. That quickly gets you down to the metal... Then you can sand blast to white metal pretty quickly...
I had another thread I had started about a problem with the tear down... It has some great info .... here is the link... It is about removing the frame bushings. ....

My old Big Bear nearly left me stranded but I managed to limp back to my garage just before it died. Now No Spark. I’ve changed the obvious, inexpensive and easy parts- spark plug & coil without any luck.
Ive stripped it down and traced all of the related wiring, checking as many connections as I can but no luck again.
Next I pulled the cover and accessed the stator housing to inspect and do some resistance testing to ID a possible short.
Here are my readings:
Source coil- 325 ohms
Pickup coil- 225
Can anyone tell me if these are good numbers, and if good, where to go next?
I assume my next purchase will either be a new stator or CDI, but since neither of these tend to be returnable items I want to be as sure as I can I’m gonna get a resolution to the problem!!

I have a 2003 LTZ 400 that i bought a few days ago. The quad was running fine until last night. I let my brother ride it down the street and back and i didnt notice anything etong with bike. Then my neighbors friend came over and said "can i ride it?" I said "sure" so he ripped it down the road all fine and when he got back it died right in front of us. My brother said it was dieing on him also. He also said that he wasnt using the clutch to shift. I told him he was an idiot. Im throwing that in there incase that caused a problem as well. But today i go to check it to make sure its getting fuel which it is and replaced the spark plug incase it wasnt getting spark but it is. So i started it and it was having a problem starting then i got started and was reving at idle high. So i took it around the block and it died on me a little bit down, so i try to restart it and it started so i kicked it into 1st and it kinda launched on me and started going with the clutch all the way in. Then it died right after and wasnt running right during that process and was idleing all over the place and just died and now i cant get it started it again. Before it would start without the choke or priming it. It would start real quick now i cant figure if it needs to be rejetted or something else. Air filter looks clean also. But any help would be gratelly appreciated!
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.
Hello, well back to where I was last year with this carb. Took my 250 to the mountains for the first time this year and blue smoke, too much gas again. I can't believe that this carb gives me this much trouble. Seems like the choke is stuck but the cable moves freely. Anyone else ever experience this issue? Do you think a new choke cable would maybe resolve this?http://www.quadcrazy.com/atvforum/images/smilies/arghh.gif
OK it was the choke. Put on all new cable and plunger and she is running 100% again. So now the question is, is the carb getting worn out where the plunger needle goes in the small hole and when I use the choke the needle end doesn't get lined back up with the hole?? We'll see how it runs and now that I know what the issue is I can always pull the choke plunger out and reinstall if I start having this issue again.
looking for direct shift shifting lever that properly fits my 2003 Yamaha warrior 350 and fits my foot the same as a stock 2003 Yamaha warrior 350 shifting lever fits my foot
