I have a 2012 Bennche Bighorn 700X.  I bought it used.  It had been sitting in a field for several years untouched.  I put a new sun gear in the shifter, new shifter linkage due to the old one having been patched, and a new battery (and of course fresh fuel).  The machine cranked and ran beautifully.  I had it over a year and then the machine quit running.  As it would not stay cranked, I narrowed the problem down to a bad IAC valve.  I replaced it and it ran as good as new/old.  Fast forward, the machine started to act like reverse wasn't catching and would not always back up when in gear.  Then forward quit.  I assumed a bad CVT belt and got one.  Started removing the bolts from the cover and (3) just turn in the housing without coming loose.  (2) are on the bottom, so very little room to do anything with them.  I tried cranking the machine again to see the belt move since I can move the cover enough to see the belt and now the machine will not crank.  It turns over fine.  It gets gas to the injector and has spark.  I can spray cleaner down her throat and she would run until it ran out.  I have replaced the IAC twice and put a new injector with no change.  I went out and put the old injector back in to see if that made any difference and, well, it did.  I tried to crank the machine and the starter is stuck trying to turn the machine over even with the key off.  I have to disconnect the battery to stop it.  Before I shoot this thing, what am I missing?  Is this an ECM problem or something else I am not seeing?  Been dealing with these Gremlins for over a month now and weeds are starting to overtake the motor due to it not moving.  I would love to get the thing running first and any ideas of getting those CVT cover bolts out would be extremely helpful.  Thanks in advance.

I have replaced the injector, fuel filter, and IAC valve.  I get plenty of fuel up to the injector.  So, after finding the battery was dead, I put the charger on it.  It never would charge.  Pulled the positive cable off and it charged.  I attempted to reconnect after the charge and the starter engaged with no key in the ignition.  I let it sit for a while, went out and pulled the wiring to the solenoid by the battery, checked it all the way to where it connected, and then reconnected the battery cable.  Turned the key and everything is back to normal with no zombie/ghost starter.  I sprayed cleaner down her throat and she starts and runs.  She runs longer than normal and then dies.  Turn the ignition over and it cranks and dies immediately.  If I keep my foot in the throttle, it will run.  I know the last time it did this was the IAC valve being bad.  I know new parts can be bad.  Could I be looking at another bad IAC valve or something else?

      Hisun 700 won’t start due to Break switch
      By Some random dude
      2015 Hisun 700 Utv
      the break pedal seems to not fully throw therefore it won’t engage the switch in order to start. 
      it throws enough to stop the UTV but not enough to engage the switch. 
      I used it this morning, started fine, did some work then shut it off to talk to a neighbour and it wouldn’t start after. I can hear the injectors working but the break pedal doesn’t seem to go all the way down.

      New AMP Pro Owner

      Just received delivery of a 2024 AMP Pro.  Thought I'd start a thread with my impressions as I use it and learn more.  There doesn't seem to be a whole lot of real-world usage information out there on this model.  Hope this will help others as they research.
      Intended Use Cases
      Fire mitigation / slash removal from a 5 acre forested and well-gamble-oaked property.  The previous owners thought as much about fire mitigation as I do about fashion: not much. Snow removal Stump pulling General hauling (rock, lumber, etc.) Weimaraner energy depletion.  Wasn't an original use case, but a nice added bonus.  Experiences So Far
      Wasn't impressed that two of the bumpers on the underside of the bed where it sits upon the frame were missing.  The metal on metal contact has damaged the powder coating and the frame.  I expect a little better QC.
      I've only put a few hours on it, so not a ton to report on usage.  It isn't quiet; it's silent.  I can't even detect an electric note from the motor. I removed (and subsequently replaced) the motor cover noticed that the motor is German and made by Schambuller.  The motor controller is Italian and made by Dana TM4.  Given the operating specs of both I found on the web, I suspect both are higher quality than the previous Navitas (which is supposed to be decent).  The motor is rated at 25 hp and 71.5 lb-ft of torque.  It feels very powerful.  All the torque is delivered instantly, if desired.
      The bed is huge and has an electric dump as standard.  Great feature but would like it to go up a bit more.  Probably not feasible from an engineering perspective, but I want and I need ;).
      Power steering is nice, but vague.  Probably common to many UTVs, but I am accustomed to more direct results from input.  Plan early and plan often.
      In our first full day of usage, we hauled about 1/2 as much slash as the entire rest of the year when I was doing it by hand cart.  I may get fatter, but I'll also get more done.  After a few days of usage, the battery meter has gone down by 1/10th. 
      Until next time...

      Sector E1 Battery change out
      By Gorj
      I am going to replace the batteries in my E1. I am not interested in the high cost Lithium or the expensive 6 volt dry batteries.  I am considering four 12 volt deep charge marine batteries. I have a source for 810 amp units for about $100 each.  I have no worries about reprograming the charger because it went out a few years ago and I replaced it with generic golf cart charger. When I decide to do this, I'll keep you posted on the results.

      Want a new work UTV; who and what should I look for?
      By FTG-05
      I want to ditch my Kubota RTV-XG850 and its moronic twitchy throttle design flaw, get rid of the problematic engine and the 40 mph purposely throttled speed.
      So far, I'm looking at the Honda Pioneer 1000 and the Polaris Ranger 1000, both of which have 1000-1500 lb payload bed capacity.
      What other makes and models should I be looking at?
       
      Thanks for the help!
