I'm working on a Coleman UTV 400 that has a rough idle, owner has had it for about a year. When I say it has a rough idle, it doesn't have the continuous smooth running sound. At times you can hear it kinda skip, sputter, or like the RPM has fallen (RPM stay constant according to the gauge) It's not as bad as it was after I replaced the fuel filter and fuel injector (both are Chiki) not sure if that is a quality brand at this point. Checked the spark plug, it was a little foul, but not too bad. (Since the engine is still idling bad I'm going to replace that) Cleaned the throttle body making sure the carbon and soot has been removed, and the air-filter has been cleaned. New fuel is being used so it's not old or been standing. They did tell me that they were using non-ethanol fuel, not sure if that would be causing the issue. Next two things I can think of that maybe the issue is the O2 sensor or the valves need adjusting.
Thoughts and suggestions? Thanks in advance.

i just purchased a 2024 g2 z force 800 and would like to power some accessories with out hardwiring would a 3 way cig lighter adapter work plugged into the 12 volt outlet on the machine each splitter plug has on/off switch accessories include led light bar, micro midland 2 way radio and maybe a bluetooth soundbar obviously wouldnt be running these at same time.
We own a 2020 Kubota RTV-XG-850, with only 400 hours on it and it has been at the dealer 3+ months. We were just informed our engine failed and requires a complete rebuild at only 400 hours! There is a loss of compression in cylinder #1, which is causing backfiring and a loss of power. There is also excess gas in the engine oil.
We are just outside of the manufacture's warranty period, and they are serving us a nearly $5000 repair bill, with only a 90 day warranty.
A member at a different forum had the same issue at 22 hours and fortunately, his RTV is under warranty. He was informed that "short tripping" (as Kubota describes it) causes gasoline to enter into the engine oil, which causes a dilution of engine oil and eventually leads to catastrophic engine failure. This killed our engine in under 400 hours!
Is anyone else with a 2018-2022 XG-850 running into similar issues?
