2007 Polaris Sportsman 700 not firing

Recommended Posts

I have a 2007 Polaris 700 Sportsman. Bike was running fine but started sputering before the last time I parked it. Now the bike will not start. The bike turns over and is getting plenty of fuel. It acts like the spark plug is not firing. I have replaced the spark plug and spark plug wire but still it acts like it is not firing and will not start.

I am now down to checking the spark plug coil, CDI, Stator, and the trigger on the stator.

Any ideas or suggestions that can point me in the right direction would be greatly appreciated.

thanks.:wacko:

To be sure that you aren't getting spark, take the plug out, connect it to the boot and ground the plug to the motor. Crank the motor over to check for spark. I think you are probably right, but it is best to be sure. If it is indeed lack of spark that is your problem, then you have are on the right track, I would, however, check the kill switch and key switch and all connections first. You want to rule out the simplest and cheapest problems before you start spending money on more expensive parts.

BTW, JB68, Ricky Stator is a brand name, they make aftermarket ignition products and even other hard parts like a-arms and such.

      Hey guys, new here, but haven't found ANY answer to my specific problem on a Suzuki dedicated ATV forum, so here's to hoping!
      I acquired a 95' Quadrunner 250, 4x4, (LT4WD) for practically nothing with no spark. The PO had tossed in a used stator which didn't fix the problem... so I went all routes (though cheaply) to narrow down the initial problem of no spark. 
      Plug, coil, CDI (caltric) and stator w/pickup (caltric) were purchased and installed. And it RAN, but bogged horribly and would not rev past 1/4 throttle. 
      I checked fuel flow, vacuum lines, all the normal stuff, no issues. I decided to check the valves and cam... well, there was one problem. The cam was 1mm under the lowest spec in the manual. So, in-came a new cam, Stage 1 Hotcams... also threw in a new set of shindy valves, lapped them, replaced the valve seals, and the timing chain. 
      Back together again (w/stock airbox and new oiled filter). Now it idles even better, still boggs at 1/4 throttle, but will rev past it if you hold the throttle open for a second. Ahaha... success!
      So I was able to ride it above 1/4 throttle once I had momentum... could shift through the gears, all was good as long as I kept it over 1/2 throttle. Took a long enough ride to break in the cam properly at least so I won't have to worry about that. 
      Now, I start fiddling with the carb. It's clean as a whistle, stock, with stock jets (new replacement Mikuni jets). Same problem. 
       
      I start thinking, maybe this is fuel related and the bike is having an issue transitioning from idle jet to main jet... so I LOWER the needle by raising the clip 1 spot. Now it revvs up in neutral with no bog, but it boggs about the same trying to ride it. So I move the needle down again with the clip on the top slot. Better, but still has a bit of bog at 1/4 throttle. 
      The last bit of advice I got was to ditch the CV carb... so I sprung for a brand new Mikuni VM30-83 round-slide. Bolted it up, blew into the vacuum tube to fill it with fuel (no vacuum port on this one) and she fired right up... but there is still a bit of bog, it's just masked by the fact that I'm not waiting for the vacuum diaphragm to open. 
       
      So I feel like each little step brings me closer, but not perfect. I'm now wondering if this is still in-fact a carb tuning issue (I have some jets I can fiddle with and maybe lean-out the idle jet a little.) OR if the cheap-a** Caltric Stator/Pickup is what's causing these issues. 
       
      I have a 95' KingQuad with 400 miles on it... like new.. runs like a top... I've tried both the stock QR and the Caltric CDI boxes on it, and it revvs up and runs like a champ. 
       
      The only unknowns between the two systems are the carb, and the stator/pickup. My next step in troubleshooting is to rip apart the King Quad and test it's CDI on the Quadrunner... but considering there is no change to how it runs I doubt it will lead to a solution. 
       
      HOWEVER... I tried the stock CDI just recently after running the Caltric this whole time, and the bike runs like garbage. Hardly idles, and won't rev up at all. So, that is my one smoking gun telling me that it's either the pickup coil or the stator itself. 
       
      Has anyone had a problem even CLOSE to this? I can't image the carb would be causing this many issues, especially going to 2 different ones, both with stock jetting to OEM, and exhibiting the identical symptoms... the only change is when different CDI's are plugged in, or when the needle valve leans out the mixture. 
      Also, I checked the piston, rings and bore when I had it apart and they're like-new... no scoring, rings are loose, cylinder is still round and has honing marks still int he bore. Stock piston, stock bore size and it has 160psi compression. Battery is brand new, and I've tried 3 different R/R's, none of which change any symptoms, but slightly vary the charging voltage by .2-.5 of a volt depending on which unit. Also tried a new coil which changed nothing. 
      ANY help would be appreciated. Too much invested to not get it running right.

      Hello all just recently acquired this atv which as you can see in the pics that it has had an unsheltered life. i did get it running and put some used tires on the front.
      It still needs a bit more well needed maintenance, chains tightened and oiled. needs an airbox or air cleaner and other misc items.

      Hey, I just bought the kids a LT80 and noticed a small puddle under the machine after they were riding it for a bit. I'm wondering if anyone knows why the fluid coming from the fuel shut off is a red colour, and would have any ideas of where this issue is coming from? I haven't had a real good look at it yet, thought I would ask first.
