My son has a Big Horn 400 Explorer UTV that won't start.  He pulled the fuel line off after the filter and there was fuel flowing.  The spark is good.  He said before it quit it would start to bog down when he drove it up an incline.  The plug was dry.  We tried to pour a little gas into the carb but it may not have been enough.  We sprayed starting fluid into the cylinder and it still didn't start.  It didn't sound like it even tried to fire.  Fuses look good.  It is a 2020 model we bought last November so the carb shouldn't have any gas gelled to plug it up.  I think the next think I'm going to check is the compression just for giggles, shits and grins.  Any suggestions what else to do next?  Thanks.  Bob

TapBoss, we ended up tearing the engine down and found the bolt holding the sprocket onto the camshaft for the timing chain worked its way out.  The rest is ugly as a dead hog.  The valves and pistons were obviously damaged beyond repair.  Warranty was going to replace the UTV but imports have been blocked but a new engine was received and replaced.  Power Sports are slow getting payment to the service center.  Right now we are lying in wait with baited breath patiently awaiting the service center to be paid so I can get the UTV back.

      Loud UTV and communication
      By mac66
      Just bought a used UTV, my first SxS.  It is extremely LOUD!   Was thinking of wearing shooting ear muffs to muffle the noise but then my passenger( wife) and I couldn't hear each other over the shouting we have to do now.... On the other hand we sometime ride with my brother and his wife and would like to be able to communicate. We throught about FRS and/or GMRS radios (we are licensed for GMRS) but we'd have to wear earphones under our ear muffs. My state doesn't require helmets to ride UTVs.
      I suppose if everyone has a cheap FRS/gmrs bubble pack radio with a ear phone we could all talk to one another. Just wear an ear plug in the other ear or ear muffs.
      Looking for suggestions.

      Fuel economy
      By LongSun
      I can not find it on the board, so I'm afraid I'm the only cheapo on the forum.
      What is the fuel economy of the Hisun HS590? (I guess it is the same as the HS550)
      I count in liter per 100 km, but if you use MPG it's okay with me, but please tell if you use the US or UK MPG!

      2012 Bog Horn - no power
      By TomW
      I had a problem 6-8 mo ago when the unit would not start . But you could see power on the dash. The starter solenoid was replaced and it has been fine until yesterday. When I started it up I noticed a high pitched noise coming from under the front. Like a alarmbuzz ..It seemed to drive fine so I went ahead and used it off and on for a hour or so . The noise would not go away . I parked it in the shed and lifted the hood . It seemed to be coming from the battery compartment ( where the new starter solenoid is) I jiggled the connections and the noise changed timbre and then the machine went dead. No power at all . No lights . When you cross the two poles on the starter solenoid ( previously last year it would start and run ) nothing. Checked the battery and it is fully charged . I checked the fuses inside the battery box and they all looked good  but I must be missing something. Anyone have a clue what I need to do next to R&R. The closest repair place is 2 hours away in Mississippi . Any help would be appreciated.

      Kohler EFI Fuel Pump Power
      By NDV45
      I have  2008 Cub Cadet Volunteer Tracker.  Was running fine, parked and next morning electric fuel pump inop.  Checked voltage had 4.2 volts.  Swapped relays in fuse box, checked all fuses (good) and still low voltage.   Does the ECU control the voltage to the fuel pump or which relay controls the voltage to the pump?
      Have checked all wiring and not found any place it could be shorted (not saying I may have missed something). I am at a loss.  Need Help Please.

      2017 Challenger 500 No power on take off or hills
      By great8redsfan
      Okay folks. I have a low power issue. Been like this for a few years. Place I work at bought 3 and all have lost most of the pulling power.  They gave them away after local shop worked on one for 3 months and it had great power for about 1 month and then crap. They replaced throttle body, fuel injector, spark plug and IAC motor. Seat belt switches have wires cut and left open so no seat belt warning light anymore. It revs to 6k rpm in neutral but when put in gear and take off in low it just doesn’t seem to want to go anymore. Running 93 octane fuel with Stabil.  Any ideas greatly appreciated. I dont have a scan tool but no codes on dash. If held to floor it pops a little and runs almost 5K rpm but if I let off pedal about an inch it smoothed out and revs up to 6k rpm.
