2005 polaris sportsman 700 efi keeps fouling plugs after 1 hr of riding I am running fresh rec fule and ngk plugs
Hello, good answers here and i dispute none of them. I just happen to have had the same experience. It baffled me that I kept fouling plugs before I could ride it at all. After quadruple checking everything 10 times guess what it was. As always, it was back to 4 stroke internal combustion engines 101. Onlya a few basic things are needed-,1.) Air 2.) Fuel 3.)!Compression of the mixture of 1& 2, 4.) Ignition if that air/fuel mixture, then finally 5.) Exhaust
I had it all covered but knew I had a fuel issue as it wouldn't rev quite like it should've. So I knew it was fuel despite my going through $40-$50 worth of NGK's. It was lean, not enough fuel, but I could smell it when I pulled the plugs every time.
Come to find out, the fuel line was obstructed as I hadn't routed it carefully enough and therefore fuel was lacking, I started it, satvthe gas tank on an old workbench with the machine running and I knew it I had it when it revved to the rev limiter with ease. It was a a "kinked" Fuel Line. I carefully placed the tank the tank on and routed the fuel line carefully, revving it as hard as it would go along the way as I tightened the bolts, I took it for a test ride and it was as well as new! ! It's just that simple and that inherently simple sometimes so don't neglect the small stuff. Check air, fuel, and spark, you'll get it. I changed the plugs once more and it ran perfectly until I sold it and it still is as good as ever. Same issue with a GSXR-1000 Motorcycle I had around the sane time, so check it out 10X over if necessary, you got this.
If this has been helpful please let me know by clicking the green button and that is the best indicator to me that I am doing what I'm supposed to do by helping others and in all honesty I'm doing this 100% free, I expect nothing for it, I just hope this helps and if so please let me know, if it's not too much trouble perhaps you leave a 5 to 10 word review or recommendation to let others know that this is helpful, if not no issue I hope this helps and have a great day good luck and may this beef most helpful to you and others, it really does get a ride back to the basics about nine times out of 10. I'm not just talking out of my rear end here, I've been an ASE certified master mechanicb and certified in many different areas of automotive and equipment related technology including off-road vehicles and everything from bulldozers to bobcats to Ford and Chevrolet half ton trucks/God knows what all it is really been but a whole lot of cases go right back to the basics. If it's a diesel the Only part of the equation that is different is the ignition station as a diesel engine does not have a traditional ignition system and realize oh nothing but heat and high compression along with the diesel fuel and air mixture which in turn causes internal combustion resulting in the same Process although be in a different way Which is different but there again is based on the same mechanical principles because the heat created Along with the compression of the diesel fuel and air mixture is enough to ignite and propel the Engine forward to propel the drivetrain to do whatever it is you would like for it to do and it doesn't require a traditional ignition system as it only relies on heat so it's slightly bit more involved to diagnose a diesel system but this obviously is it and if so it's still not that big of a deal, once again don't ever neglect the small stuff because it will get you every time if you don't pay attention to the fullest! Again please let me know if I've helped you and, I certainly hope I have, have a blessed day!
