Many things could cause this. If it is oil fouling maybe rings or valve guides, hope its not that. If it is dry powdery fowling it probably flooding. I know its fuel injected, the only thing i can think of there is replace the injector, but before doing that i would run some fuel injector cleaner through it and see if that helps. The other question would be how does it run, good, sluggish acceleration, jerky accelertion. What im getting at is to properly diagnose i need a little more information on how its running. There may be other electronics involoved that control the fuel injector.

Yup.. What Gw says..  What is this fouling like ? Wet or dry, oily or powdery, baked hard or fluffy ?

And how does the bike run ? When did it last get a tune ?

Is the fuel fresh ? Have you inspected the air-filter ? Is the plug the right one for the bike ?

      2012 John Deere Gator 850i RSX Idle Problem
      By N00bie
      From Arkansas. Just bought a 2012 Gator 850i RSX because I could not pass up the price. BUT it has an idle problem. So, to be honest, I joined just to get a service manual. I have a choice: 1)Buy a hard copy: ~$100; 2)Buy a CD ~$35.00; Get a direct download for free posting 10 times; or get a download for $29.00 (subscription). Haven't decided what to do yet.

      2015 Suzuki Brute Force 300 will not idle...
      By Louznmemind
      Howdy y'all, I'm trying to fix a neighbors 2015 Brute Force 300. Came in with hard to start and won't idle except on choke issue. I pulled the carb and found the pilot jet as well as the emulsion tube partially clogged. Cleaned up everything, put it back together, still having issues...  It will start right up on choke and will also start off choke if you give it just a touch of throttle but it absolutely will not idle unless it's choked just a touch. Also, excuse my ignorance but I'm assuming the "dial" thingy attached to the carb that turns in and out is for setting idle??

      1997 Yamaha Kodiak 400 fouling plugs
      By Drillbit
      Hey all,
      I need some input on a problem I'm having with my Kodiak 400 that keeps fouling plugs. First off, I've done a lot of work to this thing, most of it all in good fun. Brake work, cv joints, u joints, carb kit, checked valve lash, compression good, changed all fluids, etc... My problem is it keeps fouling plugs very quickly. I can put a new (manual recommended plug) in and it starts right up, runs great, idles great, picks up good. Doesn't stutter at all. I ride it for 1/2 a mile, it cuts off and won't start back up. I let it sit overnight thinking maybe it got to hot. Try to start it the next day, nothing. Put a new plug in, fires right up, runs great for another 1/2 mile or so, dead. The plugs come out and look carbon fouled with dry black soot on them. I don't know if this is a fuel/air mixture problem or a ignition problem. A couple of things that I noticed is I never need to pull the choke out to start it. Also, when it starts it automatically idles high like an automatic choke would do, then it comes back down to a good idle. Also I noticed that the air/fuel mixture needle valve screw does nothing when I adjust it in or out. I can screw it all the way closed and the motor still runs and idles good. Any advice would be greatly appreciated. I'm almost leaning to a ignition breaking down the plugs??
      Thanks!

      Have you ever purchased a quad from an impound auction?
      By DarkRider
      This is something I'm extremely curious about. Has anyone ever attempted to buy a quad (or any other vehicle) from an impound lot? I've always wondered if this could be a bargain, or a waste of time. Google searches do turn up some helpful results. Looks like the state of NJ holds auctions online which I'd be a bit hesitant about.
       
      My online searches haven't really turned up any results of anyone buying an ATV this way. I'd be really curious if anyone tried this, or knows someone who has. I've actually found a couple pages with online auctions for my state, but none had ATVs.
