  2. Polaris Trail Boss
    Hey there Shot in the dark but I was wondering if anybody might be able to to help me out. I'm trying to get my 1999 Polaris Trailboss 250 2x4 to get spark. I bought all new stator, CDI, and I have the magneto. I can't seem to find a wiring diagram for it or anyone who knows anything about ATVs...
  3. Polaris Sportsman
    Couldn't get spark, so I replaced stator. I got good spark, but lost it when I put the CDI back up in the frame. Used an ebay CDI and got spark again (despite being 1/2 the size as original and having 1 less wire than the machine-white/blue wire I think). Ran well. Noticed that I would only get...

    Hello, I have a 99 Polaris Magnum 500 that I'm stumped with. There are 3 black wires (kill switch circuit I think) that go to 1 black coming from the CDI. I've isolated each of the 3 from the black side and connected them 1 at a time and each one kills the bike. I've traced them to the all...

    How do I replace the CDI on a 1998 Xplorer 400? Reading this forum helped me diagnose that the CDI was what needed to be replaced. I'm just not sure where it is and how to go about replacing it now that I have it in hand. Please help! :)

  8. ATV Repair and Maintenance
    Recently picked up a 1000 mile 03 Sportsman 600 from my FIL. It would run but fall apart at partial throttle backfiring out the exhaust. He took it in for service shortly before I purchased it, and they found one fouled spark plug. I then got it and it still would fall apart and backfire. I...

    It has recently come to my attention that certain Polaris vehicles with claimed Capacitive Discharge Ignition (CDI) actually has Electronically Controlled Inductive Discharge Ignition (ECM or ECU unit). From Wikipedia: As ignition technology developed, engineers realized that a functional...

    Been having some issues with my 2008 Sportsman 500 HO EFI. Back in the fall it kept stalling when coming to a stop. Finally got around to checking it out over the winter and determined that the rectifier was going bad. The voltage output jumped back and forth from battery voltage to 14 volts...

    I have an 07 Sportman 90 that has run perfectly since the day I bought it new. The kids grew up and I sold it, to my nephew. I rolled it out of the truck, started it, and his boy rode it off. After about 100' it had problems. It idles fine, but any throttle just bogs it down and it chugs...

    Hi, my son has an '05 Phoenix (200), we had a problem mid summer with backfiring and idle issues which disappeared when we turned the headlight on. Assumed there was therefore an issue with the voltage regular. Replaced the regulator and it ran great (without the headlight on ;) ) for about a...

    Hello all, I have a 2000 trail boss i rode for a year. it ran very rich (plug black and exhaust smelled of gasoline) once it got warmed up the engine would bogue down or hesitate after 1/2 throttle.

  16. ATV Repair and Maintenance
    I have a 2007 outlaw 525 irs It's sat a little while then I could get it to start with starting fluid, so I re jetted it with the jd jetting kit and cleaned the carb completely. Now I know it's getting fuel and turnes over, but now it's not getting spark, at all. Very annoying other posts I see...
  17. ATV Repair and Maintenance
    Hi, new member here, could really use some help. No spark or intermittent spark. The white/blue wire from the CID box to the coil is grounded. The brown wire of course is ground but the white/ blue wire should have voltage when cranking correct? With this wire showing to be grounded, do you...

    My 06 Sportsman 450 wasn't charging anymore so I replaced the bad stator and crankshaft position/pickup sensor and now I'm recieving the charge but my RPM's are incorrect.. Not even relative to actual engine speed I can a steady high idle and watch RPM go past 4000 at which point engine begins...
  19. Polaris Trail Boss
    Hey guys, I'm new to the site. But I'm needing help with finding a CDI Box for my bike. When I picked up this bike I didn't realize how expensive a new cdi would be (around 200 new). I haven't had any luck finding any used ones, so I'm hoping some of you can give me an idea where i can get a...

    Ok so I have spent the last couple days tearing this thing apart testing wires without a service manual (not for lack of looking) figuring out what wires run to where and what they do. I have found that when I unhook the wires that run from the key and kill switch to the black wire that runs to...
