I recently (like yesterday) bought a secondhand  hisun  400cc 4x4 SxS. It’s a one owner 2012 model only done 125 kms. It runs rough and won’t idle  for long without cutting out., even when it’s warm.  Here’s what I’ve done to try to sort it without success: cleaned air filters, cleaned spark plug, emptied old fuel and replaced, replaced fuel filters. I notice that there is a hose coming from the carburettor (on drivers side). It goes to a T piece but  neither branch connects to anything and I can’t seem to find any places where they would naturally attach.  Any suggestions appreciated.

      2021 Massimo MXU 1000 Runs Rich
      By ToughLuck
      I have a 2021 Massimo MXU 1000.  Last winter the front drive shaft sheared off inside the motor and it was cheaper to buy a new motor than to take it apart in order to remove the front drive shaft that was broken inside the case…
      Now it is running rich, seems to maybe be geared too high, does not accelerate well once you hit about 28mph.  I’ve replaced the O2 sensor.  MAF is next (I accidentally ordered the wrong one, but when I removed the old one you can clearly smell fuel).  
       I’m not a motorhead but I can turn a wrench.  Any ideas how to get this motor optimized?  The motor has about 300 miles on it.  I broke it in as recommended in the manual.

      Just picked up a Hisun 500 that had shift issues (corroded fan gear) which I fixed. It also didn't seem to be running smoothly then all of a sudden it got worse. It seems to miss on both idle and when pushing the gas pedal to the floor and doesn't seem to be running at full power. I've been working with a local person who is walking me through some steps, but I'd like some input from this group as well. What I've done:
      - drained the fuel tank and replaced it with 93 octane fuel and added heet to help with any water problems.
      - replaced the fuel injector.
      - disconnected the battery (several times) to allow the module to reset.
      - set the valve clearance, both intake and exhaust, within specs ... intake was tight but exhaust seemed fine.
      - replaced the battery.
      - replaced the O2 sensor.
      Nothing has helped. Not sure what the next steps are, but would appreciate any expertise that can be offered here.

      Code Reader for Delphi MT05 Coleman UTV 400 Hisun
      By Homeowner A
      Is there a code reader available for the Coleman UTV 400?  I tried using the HUD ECU Hacker software and cables/adapters but no luck OBD to delphi 6 pin and KKL VAG as well as ELM327.  Will not connect.  I was able to get it to connect randomly a couple of times, but haven't been able to since.  I was able to clear and read the codes briefly.  I'm aware of the Tiny Scan 301 but it doesn't seem to be readily available.  There's a few out there but they are expensive.
