Hey all, I work for a fleet shop and we have a lifeguard ATV its a Kawasaki brute force 650. Its back firing through one carb more than the other one and back firing through the exhaust. Starts up and idles good, once you start giving it throttle it acts as if its starving for fuel. This thing gets tons of beach sand thrown at it 24/7. Things that have been replaced are:

both new carbs, new fuel pump, new plugs.

Things that have been checked: Compression is good - in range (high end of the range) also have ohm'd the coils and the resistance is within spec in the service manual. Fuel pick up is clean, no debris or restriction there. Does any body have any other ideas what it could be? Thanks for any input

      I am unable to find a wiring diagram for this UTV.  When I turn the switch to on, the contractor does not engage.  The Brake pressure switch and the parking brake switches work correctly. What else should I be looking for?  All of the diagrams I have found are for newer models and the wire color coding is different.
       
      Thanks

      How to replace throttle assembly spring?

      Just getting into this issue really. Been replacing solenoids but now I'd like to track down the problem. This time I'm not getting neutral/reverse lights or start button. Was on a creek ride when it started doing this recently. It cranks by arcing the solenoid and gives me no light or start button but if I crank with the pull cord....the neutral light and the button work. Turn it off and try to crank with the key and nothing. I'm looking into the safety switch issue tomorrow and re charging the battery. Just figured this was odd enough of a problem that you guys might be familiar. Thanks

      was thinking most of us on this forum would have another ride, so to get the ball rolling...........
      MY MAX 4 6X6 2009, now this will actually go anywhere including across the water. In the 3rd photo I had gone up the river about 30 meters then climbed up the bank, 6X6 owners call it "swimming"
