Hi All,
New here, but bought a 2022 Sector 750 brand new last march (old stock up here in Canada)
It's a good bike so far, but I have noticed a quirk and was wondering if anyone else has had a similar issue?
The issue I've had is if I leave the utv parked on any incline, not even a major incline, and leave it to sit for a while (day or two) it will not start properly. It will turn over and not fire until I press the gas pedal, when it will run and rev up, but if I let off the gas it will die. It will keep doing this until I either start it in gear and drive it for a bit or leave it in neutral and roll it down the hill to flatter ground. where it will have to sit for a while.
If I park it on a decline there is no issue. fuel is not low, it's occurred a couple times now.
Any thoughts on the cause of this? Dealership just says bring it in and let them take a look, at my expense of course.

I have a 2021 Massimo MXU 1000. Last winter the front drive shaft sheared off inside the motor and it was cheaper to buy a new motor than to take it apart in order to remove the front drive shaft that was broken inside the case…
Now it is running rich, seems to maybe be geared too high, does not accelerate well once you hit about 28mph. I’ve replaced the O2 sensor. MAF is next (I accidentally ordered the wrong one, but when I removed the old one you can clearly smell fuel).
I’m not a motorhead but I can turn a wrench. Any ideas how to get this motor optimized? The motor has about 300 miles on it. I broke it in as recommended in the manual.

Greetings All,
I'm looking for the most effective way to quiet the noise inside the cab. The cab virtually sits atop the 24hp diesel engine. It's very loud and so I'm looking for ways to make inside the cab quieter.

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.
