Just picked up a Hisun 500 that had shift issues (corroded fan gear) which I fixed. It also didn't seem to be running smoothly then all of a sudden it got worse. It seems to miss on both idle and when pushing the gas pedal to the floor and doesn't seem to be running at full power. I've been working with a local person who is walking me through some steps, but I'd like some input from this group as well. What I've done:
- drained the fuel tank and replaced it with 93 octane fuel and added heet to help with any water problems.
- replaced the fuel injector.
- disconnected the battery (several times) to allow the module to reset.
- set the valve clearance, both intake and exhaust, within specs ... intake was tight but exhaust seemed fine.
- replaced the battery.
- replaced the O2 sensor.
Nothing has helped. Not sure what the next steps are, but would appreciate any expertise that can be offered here.

Hi
I have a 2022 hisun sector eps 550. 30amp fuse is blown for eps. Checked the motor and it’s fine. Opened up the controller and found a bad diode. Dealer wanted 500$ for the controller. Just posting this in case it helps someone. I couldn’t read numbers from the old one so just took a guess and replaced it with a 100v 3amp diode.

I had to remove the relay for the dump bed due to it popping the fuse for main key power. I have tried to find a short but nothing seems to out of normal. I also disconnected the dump motor and switch and still pops the fuse. Also, when the machine is warmed up i get about 5 to 10 of work out of before it stalls. Once I can get it to start again I have to use the choke to keep it running.

Ive searched and cannot find any performance parts that fit my machine.
I have a 2020 coleman ut400.
Im looking for machined sheave kit, programmers, cdi, exhaust and intake.
I know these are yamaha rhino clones but are they rhino 450 clones?
Any info is appreciated.

Got a 2021 Axis 500.
I'm needing the head bolt torque specs.
Manual states 38nm.
But saw a video Hisun put out on YT for a 550 stating 50nm + 45° turn of wrench. Didn't think they would be that much difference on a 500 and a 550.
Seen another YT video on a 2013 500. He did 38nm.
Really only want to do this job once and done. And done correct.
Anybody got the answer?
Going to start this rebuild in a few once this weather brakes. Flooding and then snow and cold here now. But spring is around the corner and the wife has to have this fixed or a Honda pioneer may be parked in driveway soon. She has to be able to ride.
