The Harbor Freight Predator 420cc should work but verify your shaft size and rotation is the same. The Honda 390cc is a great engine but will cost a lot more.

might want to check the new Harbor freight 459cc engine.

Keep in mind that the factory matches the drive clutch and belt to the engine horsepower. Too much horsepower will smoke the belt and maybe the clutch.. your factory setup should be ok with a modest upgrade. I think your drive setup can handle up to a 400cca and would not go more than 420cc unless you plant to  upgrade clutches and belt .

      Robins subaru EH65d
      By Clyde says
      I have a 2014 landmaster S/S 4x4 model 653 4x4 with a 22 hp robins engine. I've been having problems with the govenor reving after it running a short distance. I cleaned the carb and discovered the fuel membrane has a slight pin hole (P/N 210-253). Can not seem to locate a replacement. Any suggestions? It appears this carburetor is no longer supported.

      Seriously considering buying 2022 Axis 700 from Lowes… any regrets from current owners?
      By REDfletching
      Spent today at a Honda dealership looking at their 520 side by side, then on the way home past our Lowes noticed they had several new UTVs on site, so we U-turned and ducked in there. We were impressed that all that came for $9,999 metal whole length skid plate, nice sized bed, roof, windshield, side mirrors, winch, upgrade looking tires… all of which would have added thousands of dollars to an already expensive Honda 520. Now Honda does have a great reputation from my trusted UTV experienced buddy, so it has that going for it.

      2018 Hisun Sector Crew 1000 engine die after about 15 minutes run
      By Hugh
      My 2018 Hisun sector crew engine cut off after about 15 minutes run. There is no indicator of what is wrong, no error code just die and won't restart until it cool down. I notice that the fan is not running but the temp indicator is on low temp, no overheat indicator. I checked the radiator fluid, it is cool to touch.
      Cooling fans are working, I can hear it running once awhile if I can get the engine warm up enough.  Thank you for all the help.

      2021 UTV 400 going downhill something releases to "Neutral" loud Clacking noise.
      By Robert B
      Going down a 20 deg hill engine is holding UTV back. Then something releases like going into Neutral and makes a loud clacking noise. Have to use brake to slow UTV down. Then once level it shifts back into gear. Have done shift extension does not pop out of gear.
