03 Polaris Pred Valve Problem

Recommended Posts

A week ago I could not even get close to starting it. But now I adjusted the valves (exhaust valve was not closed). i got it running but would not run without choke. i adjusted the float because it was to low tried starting it up again and it would not even start. So i went back and looked at the valves and the valve was now open again so i adjusted it and it started right up and ran perfect without choke. So i put it all back together thinking it was ready to go. Started it up and let it run for a little bit. i turned it off and tried starting it again there was NOTHING. took it apart and there was 0 compression and the exhaust valve was open again. I am completely lost need help PLEASE!!!:aargh::aargh::aargh:

      got 7 atvs off CL recently for a good price.  one of which is a yamaha warrior.  anyone know where the vin is printed on this bike?  Haha good place to start as I do not know year or size yet.  The former owner says needs exhaust ans and clutch work.  he said it ran fine until the clutch cable broke and then I couldn't get the new cable adjusted right and it would grind gears.  things I see:  clutch cable locked up again, no brakes, carb leaking (green with algae around the bowl and has gelled gas stalagtights on it), aftermarket exhaust melted the airbox so I need something different and a new air box.  I would like the use the current exhaust if I can but I have a feeling its a redneck fix as it looks like there is an ace bandage holding it to the exhaust pipe (its an aftermarket slip-on exhaust), so I'm not sure about that- lets get the bike running first.  also, battery (looks brand new, what a shame) is dead, 0 volts.  Otherwise, bike looks to have not been wrecked, and plastics are ok (it sat outside under a 'tarp' for 3+ years since it was run last).  any tips and advise on where to start first would be awesome as this is my first clutched bike (manual).
      the clutch is my main concern- I've never rode a clutched bike so I dont even know what its supposed to feel like.  lol I'm spoiled on my automatic polaris

      I am a new atv owner...I bought a used atv this summer (pretty sure it is a wolverine but reg card from last owner didnt actually say that so idk for sure). It ran great for most the summer and early fall but one day I tried starting it and it turned over a while without starting and then suddenly it quit turning over at all. No click or anything.
      I charged battery and light turns on showing neutral and heatlight can go on.
      A few other things that may be pertinent: The pull start is missing, I have a fluke multimeter but not many other advanced tools (or relevant experience), there is an extra aftermarket led light attached to front but it doesnt work either... never looked into why since I didnt need it. 
      I looked for a fuse box and didnt find one.
      Please recommend some easier things to try first as I really want to avoid taking it in if I can (having one income and 4 kids can keep out extra cash, plus I want to learn). Pictures would be awesome if possible. Thanks!

      Hey guys, need some help with my 2016 Yamaha Kodiak 700 4x4.  Was riding and it started smoking below the air box and then Caught fire.  We got the fire put out quickly with a fire extinguisher.  Many of the wires below the air box got damaged.   I purchased a new wiring harness for the atv and replaced that as well as any other damaged cables or parts that burned up where the fire was.  I also replaced the regulator, the ECU, and the starter solenoid. I also replaced the stater since some of the cables that went to the regulator were damaged.  It acts like it will crank but it won’t turn over.   The fuel pump initialized when I turn the key so it’s working.  I’ve spend $1500 on parts and no luck yet.  Any suggestions?

      Ok, so I bought a 2006 bayou 250 for 200 bucks, kid couldn't start it and had no idea why it wouldn't run, I pulled the rope and felt what I thought was valve to piston contact, he wanted 500 and I talked him down to 200 and brought it home.  Sure enough, timing was way far out, timing chain incredibly loose.  So for fun I re-tensioned the timing chain and re timed it, got about 120lbs of compression, pretty low.  I cannot get the chain very tight but the the tensioner seems to work fine, the chain guides don't look very worn.  Also, when I took the head off the valves don't look bent and the piston has no discernible marks on it.  Is this an interference engine?  I sure thought I felt some contact with the pull rope but maybe no permanent damage was done?  Anyway, I plan on doing a full top end job as well as timing chain tensioners and hopefully that'll cure it.  Is there any reason other than chain stretch (I measured it and it's ok) or guide wear that would cause the chain to be so loose?  Thanks!

      I've never done this before but after reading a few thread I decided to check my valves for the first time and to my surprise it was much easier than I thought.
      My bike is a 2005 Sp 500 HO.
      I first pulled the seat and the right side panel off, and that's it! It wasn't too bad to get at.
      Next I pulled the spark plug out and removed both the head cover ( 8-8mm bolts)
      then the side cam cover (5-8mm bolts).
      Also remove the plug in the recoil cover (14mm bolt) to see the timming marks.
      Next I turned the engine over with the pull cord untill it was at TDC of the compression stroke.
      The best was to tell that your at TDC of the compression stroke is to rotate the engine until the
      timing marks are parallel to rocker cover gasket surface.
      The cam sprocket locating pin will be facing upward directly in line with the crankshaft to camshaft center line.
      Now fine adjust by looking into the timing hole in the recoil cover and line up the upside down "T" on
      the flywheel into the center of the hole.
      Now using a feeler gauge, slide the .006" (.15mm)blade between the top of the valve and the bottom of the adjuster and adjust accordingly
      To adjust, Loosen the locknut (10mm) and check clearance with a feeler guage. Clearance should be .006" (.15mm) for both, intake and exhaust valves. Turn the adjuster with a stubby flat blade screwdriver untill the proper clearance is achieved then tighten the locknut (5.8-7.2 ft. lbs) while holding the adjuster in place with the screwdriver. Re-check the clearance with the feeler guage one last time and re-assemble the covers (72 in.lbs) and plugs.
      The only thing that i noticed was that I had to clean and silicone the side cam cover other than that I found the whole process rather simple.
      I'd give it a 4 out of 10 on the skill level scale.
      I hope this helps!
      Thanks Rich

      I have a 2000 Polaris Sportsman 500. The Speedometer got water inside of it and it sat for a long time. So now that speedometer is trashed to say the least and i need to find a replacement. I don't want to put up the cash for an oem one so i was wondering if anyone knew any good speedometers out there i could use. I've found many speedometers i like but don't know how i'd wire it up without the same connection points. Thanks, any input is appreciated

      I've already posted here once about this ATV. Lots of people suggested i check the cam and after a couple months i finally got around to attacking it. I got it all apart and got the cam/rockers out. I'm almost positive they need to be replaced, they're pretty scored up and don't look too hot. Just wanted some final opinions before i drop the money on it. I'll also take feedback on the new cam i've chosen.

      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

      Recently bought a Polaris 425 Xpedition. Main issue is that the quad randomly misfires sometimes. ONLY does it at idle. Everything sounds good. What should I look for? Haven't checked the plug, seems a bit hard to get to, not sure. Headlights flicker at idle as well, is this a sign of a weak stator? Help?
