Less than 40 miles can barely start. Dealer is working with Hisun on a number of other issues on this UTV. Can not get clear info on the meaning of these E codes this is getting. Anybody have some clear info for me?

Hello I am new here but have had this machine for about 5 years. I am having issues with it surging and sometimes sounding like a small backfire thru the intake. When putting in low, high or reverse it will struggle then go full power then struggle. It will only do the small backfire thing while in neutral reving it many times. Once in awhile it will throw a check engine light.
Parts replaced/checked:
I have checked the valve lashing, timing and adjusted. Parts replaced are the coils, spark plugs, injectors, fuel lines, fuel pump, IAC sensor, TPS sensor, throttle cable, speed sensor, primary and secondary clutch and belt.

Hello to anyone who reads this. I am Jon and I own J&M Outdoor Power, a very small, small engine repair shop. I was approached by Coleman about 6 months ago to become one of their Warranty Centers.
I recently received 3 different UT400's and a UT500 all with similar issues. These units range from 2 months to 2 years old. Customers state that the unit(s) was/were running fine, then heard a pop and a loss of power, two would no longer start. The two that would run would not achieve normal operating speed (around 20mph I would say) without redlining the RPMs. I quickly found that the Valve lash on each unit had become too large on some(both intake and exhaust) and too tight on one(just intake).
After setting the gaps to .005(I found multiple different people suggesting bigger and smaller gaps, but no definitive Coleman Spec number yet) every unit starts, runs, and achieves top speed without issue.
I don't know how many others have come across these issues, and I wanted to get something out on the web for others in the same predicament.
Please let me know if you have had similar issues.
Edit: I realize that this will not be a fix all solution for this issue, as the oil level and condition should be verified before moving to the valves. Many times improper oil conditions will cause valve lash to change. These units all have good oil and proper oil changes.

I have a DesertCross 800 that doesn't want to stay in low, it pops out when I let off the gas. No problem with the other gears. What do I need to do? Thanks.

I bought a tracker 88sx crew in 2023. It has a whishing noise coming from the front end. Starts out low and gets louder as speed increases. Took it back to the dealer and they said it was normal on this model. Any suggestions as to what may be causing this.
