New Kawasaki Mule pro-MX poor mpg

I bought a new Kawasaki Mule pro-MX a few months ago.  I've only put 45 miles on it (been using it around my 20 acres) but it has gone through 30 litres which works out around 7mpg (UK).  This seems extremely poor, as I've read some people getting about 200 miles to the tank.  It's been used occasionally to pull some heavyish loads but mainly chugging around the fields helping with maintenance or giving rides to kids.  My fields are flat/grass with no hard terrain anywhere.

Does anyone know why the mpg is so bad, and should it improve after its first service?

Wow! That's just under 1 liter per mile.  You should see a LOT of black smoke out the exhaust of that 2-cyl engine and maybe a rough running engine.  If you had an external leak in the fuel system that would be a very noticeable leak.  Being new, I would first check for a leakkng injector.   You can search for "poor gas mileage" and it will give you a few things to check.

Check your oil, since it is fuel injected make sure that gas is not going in to the oil.  if your fuel pump or if it has a carburetor either way is stuck on then the fuel is going somewhere most likely the crankcase on on the ground.  If it has a carburetor then your needle and seat are not set right and fuel is flowing out as you drive, if it is fuel injection then the fuel pump is running  too high of fuel pressure and the fuel is going into the engine's crankcase.  Check your oil level and make sure gas is not getting into your crankcase.

      trying to finish assembly "new" 2021 Coleman ut 400
      By buckrub
      Hey guys! Newbie here. I'm an old man who's better with plowing a mule (4-legged kind) than these newfangled beasts. I, and a friend of mine, just bought new Coleman sxs and are having to finish the assembly. I've been reading on this site and I'm falling on the mercy of you experts. The only way I'm an expert is that an "ex" is a has been, and a spurt is a drip under pressure. LOL First off, the 2 buggies have no ignition switches. They seem to mount on the dash, not the opening in the steering wheel shaft cover, so we ordered new ones that are supposed to fit. They are 8 inches long, and have a 4-wired white plugin which is slightly rectangled when looking at the end of the plug. The trouble is there's nothing to plug into. There is a three-wire grey plug close enough to reach the four-wire plug, but of course, they are not compatible. 
      Secondly, the blinker, light, ect. unit on steering wheel just spins around when touched. I see no way in heaven or earth to secure it. I've looked at a diagram on the Powersports site, but can't detect how it mounted. Fellows I'd be so grateful for any help with this. Me and my mule will even plow your garden for free, for your help. LOL

      Bennche 700 EFI Bighorn New Fuel pump not working
      By Nathon S.
      I have a Bennche 700 EFI Bighorn. I’ve recently been unable to get it to start. After a little troubleshooting I realized my fuel pump was not pumping fuel. This weekend I emptied the gas and replaced it with new. I replaced the fuel pump, fuel filter and fuel injector. I also replaced the battery, spark plug and made sure all my fuses and relays were good. I have confirmed that the float on the fuel pump is not obstructed. The UTV is about 12 years old and has less than 100 hours on it. It has not run in over a year.  Not sure whats going on?!? After doing a little reading I'm leaning towards it being an issue with the ECU or perhaps a faulty wire in the wiring harness. Anyone have any ideas on where to start looking or what I could be dealing with? Any help is appreciated, thanks in advance!
