I have a 2015 kymco 450I side by side with only 800 miles. I use it to plow snow and pull a manure spreader. Yes in low.  Last night it started making a loud chatter in the engine area and shut off. Couldn't change the gear selector unless it was while turning the ignition. Pulled the belt/clutch cover off and everything was in ok shape. Took the whole assembly off and it still chatters. Looks like the splined rod towards the rear of the engine is starting and stopping in its own and that's where that noise is coming from.  Is that part of the clutch and do I need to pull that too???  Don't know how deep to dig. And where to get these parts.

Hi guys. Update on the Kymco issue. After getting zero help from the dealer i was able to figure out through pictures that this machine crossed with a 2015 Artic cat 450 snow mobile. Ebay had the parts. Fit perfect.  Clutch was worn down pretty good. Probably from pulling heavy stuff. Hope this helps anyone with this problem.

      2004 250DL DIRT DEVIL. Hey y’all, I already know this is a long shot. But I am looking for a the “prick gear” assembly that makes reverse work for my external reverse gearbox. OEM PN D250.08.103 and its assembly. I bought the kart as a basket case, but I saw that the reverse box was present so I was optimistic.  Upon starting working on the buggy I realized there was a block off plate in plate of there the normal gear would be. If my understanding is correct that means the transmission no longer has reverse gear. I figured it’s just a standard bevel gear and I could probably find a gear to make work, but I don’t want to spend the time making all the other housing parts to shim the gear perfectly. Has anyone spare parts, or figured out an aftermarket solution from McMaster? I already know it’ll be a challenge to get this box to be happy again, but figured I would ask

      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!

      Goes into gear wont move

      "Mrs. Smith" doesn't like how loud our Sector 750 is.  On a HISUN forum someone said the same thing about his 750.  I haven't given it much thought because I've been more focused on stuff that has broken.
      So, I used my decibel meter to check ours out.  4000 RPM, Low gear, under 20 MPH . . . . 97 decibels.  That's above most ordinances, even state boat noise limits.
      AI Overview Ninety-seven (97) decibels is considered very loud and dangerous to hearing with prolonged exposure, roughly equivalent to a newspaper press, a loud nightclub, or a snowmobile. At this level, damage can occur after just 30 minutes, necessitating hearing protection

      Not my machine T boss 800 Massimo, < 300 hours will not shift at transmission, cable from selector knob is okay, cannot get it to shift at the transmission. Is there a safety one of the safeties I'm not holding in, I've tried the brake is something weird going on or is it  Transmission problems.
