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!

I realize this part is discontinued but im trying to find this exhaust pipe fir my dads 550. His brother who has since passed bought this mule for my dad who is now 90 and he is trying to fix everything on it. I'm willing to take a used one. A new one would be great if someone still had in stock. I'll take anything as long as it is in workable condition. If anyone has any ideas for me im open to hearing them. Thank you so much.

2022 Coleman 400 with 13 hours on the engine and the mice got to it. Every wire coming out of the steering column in one cluster has been eaten through. I tried reconnecting matching wire colors to each other and I get the left turn signal and hazards to work, nothing else. If I play around a bit I can get the horn to honk or headlights to come on but only when I connect them to the brown wire. Obviously I don't know what I am doing here. Does anyone have a picture of how these wires are connected when they are under the hood on the drivers side coming from the steering column?
Gray - seems to carry power
Brown - left turn signal
Green with purple stripe - hazards?
Pink with red stripe - horn?
Green - head lights?
Yellow - head lights?
Yellow with red stripe?
Blue?
Dark green?
There is also a bundle hanging under the hood not connected to anything green with yellow strip, brown and blue?
Other than that issue, I am about ready to sell this for parts if you interested let me know.
Thanks

Hello. I have a 2016 Massimo MSU 500. I was putting on a lightbar and i screwed up and didn't disconnect the battery so when i was taking of the positive cable to put on the power from the lightbar it sparked and now the utv has no power. I turn the key over and all i hear is a chirp. No lights or anything. Everything that comes from the battery to the jumper box up by the battery shows voltage but anything coming out does not such as to the winch or anything like that
