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?

New speed sensor is in. Same thing. Here's the fix. Put it in 4 wheel..drive slow around 20 secs. Then put it in 4 wheel lock..another 20 secs. SLOW..Put back into 2 wheel and hit the road. Hit 40 mph, No more problem.

Mine starts and idles great but will not rev over 2300 RPM and then spits and backfires.  Now after reading your solution I'm wondering if I have a speed sensor problem.  I have changed everthing and been turning wrenches for 65 years but it's got me beat.  took to the only one I could find in the Reno, NV area that would even work on it and even after he did an upper end still no change.  Haven't even tried to drive it because of the way it running.  Bought it cheap because the other rancher was at a loss also.

      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!

      program will open in old Bud program only/ but will not go in BUDS 2 to let use program ECU problem working on has new engine/ new fuel pump/ injectors/ lines/ sensors/ crank sensor maps/ and new throttle body and injectors. machine starts runs a minute dies/ on 3 rd  try says key not recognized /we put other key in and same thing happens/wait 10 minutes, you can go again/ is there a back door in the program/ also might mention unplug temp sensor and map sensor , it will run a few minutes longer / then die again.

      Onto the next problem, everything has been replaced in the charging system except the Flywheel Rotor, I have it torn apart all the way down to said rotor, but it is suggested that a specific puller is required, and a compatible rotor seems virtually impossible to find.  I can find many like it, but this one is mine scenario for those that get the reference.  For all I know I have the last Massimo Buck 400S on the planet and will never find another part again, but who knows.  Any ideas, help or otherwise that anyone might have would be greatly appreciated.

      Hit a rock last weekend and trashed my front A-arm and axle on my Outlander. I’ve been looking around for reliable sources for replacement components. A lot of listings online look a bit hit or miss, so I’m trying to figure out what’s actually worth trusting.
      Has anyone here had good luck with dealers or sites where you can buy genuine Can-Am spare parts online without worrying about quality issues or fake OEM stuff? I’d rather pay a bit more and get the right fit than deal with problems later.
      Any recommendations appreciated.

      Hey all, I was just wondering what you guys consider a necessary upgrade or spare part to have or mod onto your machine.
      I'm going for a kind of shtf survival rig that's not going to be SUPER heavy and I'm looking at getting:
      A spare belt (I keep seeing this mentioned everywhere I look so it must be important)
      A spare tire and mount( So would I need a jack like one from an old jeep or something else?)
      Tire chains for the winter
      And maybe a cargo bed upgrade so things don't slide out.
      Bumpers because duh.
      I already installed high output lights and have a windshield, roof, back window, and winch. And I outfitted a Molle panel for the back of my passenger seat with extra supplies like food, first aid, and spare mags.
      Any advise on increasing durability, longevity, and having something on hand because it's absolutely necessary would be a plus.
      Thanks so much!
