Before I offer any more useless advice, please refresh me on what type of vehicle we’re talking about

Yes. And I’m sure the open tread design is also contributing to substantial vibration and noise

Did you maybe overfill it?

What have you checked?

I’m not trying to be trite or dismissive of the loudness. My 500 is louder than I would like as well. But a simple set of foam earplugs will protect your hearing. It will be costlier and way more work to actually make it quiet. My next one will definitely be quieter. 🙉

I had been driving for about 15 minutes, everything fine. All of a sudden the engine was surging, losing power, would run with 1/2 throttle or greater and was backfiring badly. Luckily I was close to home and got it back. The tipoff to me was that I thought I was hearing intake noise. Sure enough, the rubber boot which connects the air cleaner and intake piping to the throttle body came loose. Obviously the computer was confused. It turned out to be an easy fix, but this is now added to my inspection list. Just thought this might help someone else.

Thanks for the suggestion

On mine , in neutral, wide open throttle for 5-6 seconds. Sounds scary, but that’s how it’s done. I have a 2022 hisun 500 Pop Bob

How fast will it travel? Seat belt fastened? Possible fuel filter? Fuel contamination? Do an ecu reset. Pop Bob

Thanks for the file. For those who do not have a 3D printer, I cut the two front seat belts on a junked Chrysler minivan and used the clips. Pop Bob

First change at 10- yes. Filter too of course. Every 25-30 after that is fine. Make sure you use oil which is JASO compliant Don’t forget to put a squirt of grease in everything at each oil change. I also change my fuel filter every other oil change. Don’t know where you live, change your air filter annually. More if you drive it year round or in dusty environments. Have fun, enjoy your machine and welcome to the forum Pop Bob

Were the pieces hard like straw, or pliable like some sealant squeezed out into the interior and then broke off ? Does it run ok? I would definitely follow up in 5 or 10 hours with another oil and filter change. Good luck Pop Bob

I’ve not done one yet, but everything I’ve read or watched says no grease. Pop Bob

I’m ready to buy a second machine. I looked at a Gator and a Mule. They are larger than I want. Something more trail size will be better. That being said, I do not wish to purchase from a big box store again. Can anyone recommend a good dealer who sells Hisun based machines? Also, any thoughts on a machine with enclosed cab, HVAC, and modern electronics Pop Bob

Welcome. You and I have probably the same machine. I’m one year, and a hundred hours into this unit. I have to say, I’m really enjoying it. It does a great job for me. I find it easy to work on. Well, easy enough. Watch your temperature, keep your fluids and filters changed and keep everything greased. Check your a-arms to make sure they have grease fittings installed. Mine had the holes, but no fittings. Make sure you hold pressure on the shifter when you first move in low range. They sometimes don’t go all the way into gear. The clock in the display can be a little confusing. There’s a thread on the site which explains how to set it. Other than that, have fun. Pop Bob
