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?

Hello all. I have a 2005 Joyner sand spider 650 with the dreaded broken output shaft on the transmission. I got ahold of a 2007 joyner commando 650 for cheap that had a bad motor but a good transmission. I got it because everything i read said that the transmission would work but it seems that it will not. Due to the commando being 4x4 it has a selectable locker and a small ring gear using a "idler" gear to turn the ring gear which make the output spin the wrong direction. Is there any way that I can make this thing work? I really dont want a commando, I like the buggy but if the trans wont work then I can only put my motor in the commando. Any help would be appreciated. I have the ring gear from the original trans but the shaft is broken and the shaft from the commando wont fit the ring gear it doesn't appear.

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!

I boughtba new Hisun HS 500. When I press the red 4wd button the icon over the front differential on the display flashes. Is this normal?
