I have a 2009 Trooper that when I first start it it runs great but after about a min it starts to cut out under acceleration but clears out when it gets revved up.  I downloaded the manual from   Joyner-usa.com   but it doesn't help much,  Mine doesn't have a OBD port on it and my son who is a mechanic said he can wire one in if we have a wiring diagram for the CPU but the wiring diagram of the CPU that is in the manual is for a 3 cylinder engine.  The manual talks about a MIL light that can flash out a code but I don't know where that is and even if I did find it they  don't tell me how to read it.  I have tried the coil and the map sensor and that didn't help I checked the TPS and it checks OK.  I emailed Joyner and all I got from them is there should be a OBD port on it and then they said they checked and found some don't have it,  No help from them. Anybody run into this problem or know were I can turn to get some help on this, even a good wiring diagram of the CPU would be a big help.

Thanks for you help

      MSU 500. Runs but will only move with full power.
      By William Carberry
      I have a MSU 500. I will start and run but requires basically full throttle to move. Does this machine have a drive belt? If so how difficult to change?

      2010 Massimo HS500 (carb model) Help
      By matthejl
      Quick history:
      Bought it about a month ago and when I test drove it, it ran good. Loaded it up and took it home. Owner said it had been sitting for a long time, but was "just serviced". It only has 500 miles on it total. Drove it around and found out the charging system wasnt working...so had to charge the battery once every week and a half or so. One day my daughter was driving it and it died. I couldnt get it to start again and I noticed there was no fuel in the filter...I first checked pulse/vacuum line to make sure it was sucking and it was. So I replaced the fuel pump with one I found local...which is for a large riding lawn mower...and it worked. Engine started and ran, but struggled at low speed immediately following running it at higher speed. It would bog when decelerating. I have also noticed now that it will backfire some on decell and die.
       
      In the meantime, I went ahead and installed new stator and trigger coil assembly to get the charging system working again (that was an issue because it would not start at all after that...but eventually found that the trigger coil was wired backwards in the plug from the factory). I have also set valves, but I set them to .005 (intake) and .007 (exhaust)...per the manual. But what is weird is the manual states its mainly for the 700 series, but "can" be used on other models. On the front it says 500/600/700. I have noticed that the most common setting seems to be .005.
       
      Anyways it still has the issue to me that seems like its running lean. Not full power now, struggles immediately running it faster, and will die and pop some on deceleration.
       
      My main problem now is that it wont get to higher rpms as fast as it did when I first bought it. It struggles on deceleration after running near top speed.
       
      Things I have done:
      changed fuel pump
      replaced stator / pickup coil
      thoroughly cleaned carb (twice)
      set valves to .005 and .007 (is .007 too loose for exhaust?)
       
      anyways it seems to have a lean problem, and wondering if you have any suggestions on what to check.
       
      Thanks

      Need help with EFI wiring on a 2020 axis/hisun 500 UTV from Lowe’s
      By Tim Barbero
      I left my 2020 axis 500 UTV parked under the carport for about 6 months and when I went to start it recently a squirrel has built a nest under the throttle body and chewed through the efi harness.  I stripped all the wires back and reconnected them with waterproof butt connectors.  The problem I have is there is one blue wire with a red stripe coming from the main harness this wire has 5 volts dc showing on my multimeter but there are two blue wires with a red stripe coming from 2 different sensors on the throttle body.  I looked through all of the bits and pieces of wiring left behind and there’s no indication that the three wires of the same color were all tied together.  Any help with this issue would be greatly appreciated.

      2018 Hisun Strike 1000 Losing spark after startup
      By Nickie Watts
      I have a Hisun Strike 1000 I have been trying to get going, it has only 39 hours on it, so I can only assume it has been sitting for a long time.
       
      The issue is it is losing spark to both coils after 20-30 seconds of running, doesn't matter if it's WOT or Idle, it will shut down.  What sends signal to the coils to fire? It has a crank sensor, I was thinking a CDI box, but I have not found one of those on the machine.
      The rear end was busted on it when I got it, So I ordered a new one and installed it only to run into this problem. I can only imagine the problem has happened over it sitting so long and not being driven.
       
      I originally thought it was a fuel problem, so I checked the injectors, throttle body, o2 sensors. Discovered the heating element in one of the o2 sensors was bad, so ordered both and also replaced both injectors just to be sure, then discovered it is only losing spark.
