2015 450i UXV dies at slow speed

Yes there is an idle adjustment, but it might be something else. Is there a fuel filter which may be plugged? If not, I’d recommend installing one. Is your machine carbureted or injected? If it runs well at high speed or high load but dies when you try to idle, then go ahead and adjust the idle screw 1/4 turn in and try it. If 2 tries doesn’t fix it, it’s probably a plugged orifice. Any backfiring?

      The rear differential lock light is on and I would like to get it off. How do I do that it is a Coleman UTV700.

      My "R" light on the dash will not go out when I take the UTV out of reverse and put it into any other gear. Is this just the light switch issue or will this effect engine performance in the other gears?

      In the market for side by side. Narrowed it down between the pioneer 1000 or defender Hd9. Looking for pros and cons of both. Any info would be helpful in my selection process. Noise, speed, reliability, ride, all of it.

      Many people have issues with the kawasaki FJ400 engine  fouling out spark plugs, after  working on a  few FJ engines and 600 series Mule's with this issue,  i can say the fix for this issue is using a slightly hotter spark plug... the factory recommends a BPR6ES NGK plug.... the Number in NGK plugs represents its heat range and somewhat odd, the lower the number the hotter the plug, at least as far as NGK is concerned. If you have  a Mule fouling spark plugs try installing a NGK BPR4ES spark plug.
      FROM NGK
      A hotter heat range spark plug has an insulator design with a longer heat flow path to the metal shell of the plug. As a result, more heat stays in the ceramic firing end and less is dissipated to the engine. A colder heat range spark plug has an insulator design with a shorter heat flow path to the metal shell of the plug. As a result, less heat stays in the ceramic firing end and more is dissipated to the engine. For a spark plug to function properly, it must have a tip temperature high enough to burn off carbon deposits (self-cleaning) and avoid fouling, while remaining low enough to avoid overheating the ceramic firing end and pre-ignition.
