Have a MSU 500 that we got from my wife's uncle a while back. We've had it running and hauling around the property but it stopped a few months ago after what I thought was running out of gas and I'm just getting to looking into it.
Had fuel to the injector but nothing coming out the injector so swapped with new injector and installed inline filter in the supply hose from fuel pump. Tried again and still nothing but noticed this time that I can't hear the fuel pump priming.
Pulled off the electrical connection and I'm getting 12V to the fuel pump but it won't run. Put it on a test bench and got it to run so put test lamp between +ve and -ve terminals on the connector and nothing. Checked against the passenger seat securing post and get a light.
Tried chasing the wire back and think that the ground is through the ECU but not 100% sure. Can someone confirm for me? And if it is through the ECU, is the ECU just grounded against the frame or is it wired through to the battery?
Thanks in advance and hope this all make sense!

I have a 2022 Hisun 750 Sector which comes with a locked rear differential. Was wondering if it would be possible to install an unlocking differential. I see that there are some Hisun made machines that come with the unlocking rear diff, such as Cub Cadet Challenger, some of the Massimos, and probably others. My concern is whether these would be a direct bolt on, using the original axles, drive shaft, and of course matching gear ratio. I've tried to match up part numbers but it seems every brand has their own number system even for parts that I know are identical. If anyone has ever done this swap or has any information about the whether these unlocking rear diffs are comparable to the Sector, I'd appreciate your input.

I swapped out the Subaru motor for a Predator 670cc. If I remove the heat shield around the muffler, The stock muffler sits in there just fine with 1" to spare.
Only problem is the exhaust exit is toward the back seat instead of out the back.
Do you all think that the stock exhaust would be okay (just as effective) if cut a hole and welded a pipe on the reversed (opposite) end? Of course, plug the old exit end. Other option I thought of was to roll a tube 180° with a 7" center line radius and finish extention of 12" or so.
Any thoughts?

Hello,
Before I invest $10k+ into a brand new UTV for the farm, I want to get my feet wet with a fixer upper and learn the mechanical side of things. I acquired a 2022 Hisun Axis 500 (Lowes-specific model) from an auction for $500. It has only 200 hours and 120 miles on the engine. It looks like the previous owner used it for ranch work and didn't drive it on trails, deep water/mud, or anything too crazy.
While it runs and moves, it has some problems. It struggles to accelerate up any incline in high and low range and sometimes stalls when I let off of the throttle or change gears. When I apply throttle in neutral, it sounds like it is struggling for fuel/air and pops. When I decelerate, there is a grinding sound coming from the clutch, which I've read to be related to the one way bearing and is semi-common. The last thing I've observed is sometimes the speedometer display sometimes will show a much higher value for a few seconds after barely touching the throttle. Based on the documentation, if a problem is detected from the sensors, the instrument panel display should have an error code rendered on the screen in place of the time, but this isn't happening. Here is a video showing some of these issues (engine is exposed with console removed):

Here is another video of the clutches in action:
I've done some research, but information on this specific unit and sister units is limited. There does seem to be transmission and clutch issues reported. I still need to check into the head gaskets. I don't have the equipment to test compression right now, but I do plan on ordering what is needed soon. I do have an order in place for some cables to read the diagnostics from the computer. There is a shop two hours away from me that works on Hisun products, but I am hoping the problem can be identified and is something within my ability to handle. Below is what I've already investigated. I am leaning towards the primary clutch needing replacement right now.
After getting it home and unloaded, I did the following maintenance/checks to it prior to operating it further:
Changed the engine/clutch oil (and filter) and gear oils using manufacture recommended viscosity Changed the air filter and checked for cracks in the air intake flow. Verified good suction. Cleaned the throttle body Changed the spark plug and verified the gap was within spec (0.6-0.7mm) Changed the coil and coil wire Changed the fuel lines, fuel injector, and verified the fuel pump was outputting the correct initial prime pressure for ignition and continuous pressure after ignition. Also completely emptied the fuel tank and made sure octane 91+ fuel is being used per manufacturer specs. Ran seafoam through system too. Cleaned the spark arrester and verified no cracks or gaps in the exhaust flow Changed out the O2 sensor Checked all wired connections to ensure they were secured and no breaks were visible Checked the belt for tightness and for any signs of wear and tear Verified 4WD and the differential lock function as expected - still hesitates and struggles uphill Verified the fan gears in the shifter are not corroded and working as expected ECU was reset after replacing sensors and fuel-related parts
Thanks!

Trying to get running a 550 Colman running but I think head gasket went bad. Do i just replace with new gasket, clean up and replace or is there more to it?
