So with seat belt on I can only get up to 20mph then it starts bucking until I get under 20 again. Diconnected the seatbelt and same thing. Reconnected seatbelt and unplugged speed sensor. Zoom..it flies. But now I have no speedometer. I have a new speedometer sensor on the way..any other ideas?

I bought this SxS brand new. A couple of years after I bought it, I became disabled. Thus it has only 47 miles and around 16 hours of use. I have no need to keep the SxS. I am in Foley, Alabama. It is very hard for me to get in out of the Challenger. I would like to sell the set, 2019 Challenger 400, trailer and uninstalled winch (this was bought brand new as well, someone was supposed to help this newbie install and we never got around to doing this). I want $6500 for the whole set OBO (Serious offers only).

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!

By HISUN Sector 750 EPS Failu
It looks bad, but the HISUN (Axis) 500 at work has had "regular" oil in it for 900 hours now. I discovered it when I googled what my Sector 750 uses, it being about time for the first oil change. This is the only side by side that the mechanic at work takes care of, and he's the type of person who knows it all. He would never check an owners manual or search something online.
The problem with someone who knows it all is all you get is what he knows.
Being on a first-name basis with the HISUN Tech Team, I've asked them what the consequences might be. I'm concerned that the clutch may be permanently damaged.
Anyone had this experience?

Hey there,
just got an old 2013 HS400 UTV - the pre-owner had a leaking speed sensor and put a new like this:

It fits but he couldn´t get it connected, he told me the plug is different. And the sensor looked different too.
Has anybody this problem, too? Plus i can´t find the counter part plug for the sensor, maybe i´m blind? Where is it located?
Thanks in advance!
