Good day I am helping my grandfather with his mule. He had it in a river and it has not worked right since.

-first we drained all the fulids and replaced with new.

-disconnected all connectors and cleaned and dried

-once we got everything dried out we got it running but very rough

- a friend has a similar model so we tried a few sensors, switched cpu and in the end found out that the throttle body was giving use problem and after talking to the dealer they said that it had to be replaced

- we replaced the throttle body and now we have a different issue

to start we have to give it a little gas(just touch the gas peddle) but

once started it idles very high and stays high, if we give it more gas it loses all power but continues to run.

have tried to adjust the idle but stalls as soon as you lower the idle

it is idling too high to shift into gear as well

pulled off the fuel line and the pump seems to be pushing lots of fuel so i don't think it is the pump( but i have not ruled it out completely)

I have been given a few ideas such as

-the air temp sensor( not to sure about that but if i short out the connector this should bypass the sensor right?)

-I have been told to test the injectors ( what pattern should i look for I am thinking circular but want to confirm)

-I have been told to re-seat the valves( not sure how this would cause it to idle high)

any help is much appreciated thank you

      2018 Hisun Sector 1000 Crew stalling but starts right back up. Please help!
      By Jon Spruill
      Hey Guys, I have been chasing a stalling condition for about two weeks now. The bike will crank up and idle fine, then after about 20 seconds it will fall on its face and stall. It happens at both idle and while running at various rpms. You can turn the key off, turn it back on and it will fire right back up without trouble. I have verified spark on both cylinders with a spark tester. I have also added an inline fuel filter, and pulled the injectors to verify proper pulse on each. Things I have replaced - (relearn procedure performed after each component replaced): spark plugs, ECU, relay/fuse box, fuel pump, & throttle position sensor - all with no improvement of the condition. The only warning light I get when the condition occurs is the oil lamp. The bike only has 14 miles. I am at a loss and appreciate any help and suggestions! Thanks

      New AMP Pro Owner
      By Xov
      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...

      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!

      Washing Mule Underbody
      By rsar
      Hey guys. I was wondering if anyone pressure washes their Mule underbody. Three years in, I have yet to do this. I'm worried that the pressure washer could damage or dislodge something but it's gotten to the point that it could use a bath. Any thoughts?

      2510 Kawasaki mule Diesel
      By TjB
      My dad has recently acquired a 2510 Kawasaki mule Diesel powered. It worked fine  few weeks and then quit driving. Put a new belt on just to see. Still not driving. It already had a new clutch. Belt turns when in drive or reverse and back wheels are off ground to test. But wheels not turning. Thoughts?
