The Hisun Sector E1 is a nice electric unit.  Is there any way to remove or adjust the speed limiter.  It's limited to 25MPH so it will be considered a slow moving vehicle. But in my province it can not be driven on the road even with a limiter and triangle. So I'd really like to get a bit more speed out of it.

Not really a possibility. You may get a couple of MPG. The motor has only one bearing (like the Ranger  ) and uses the gearbox input shaft as the front bearing .  Upping the RPM by anything significant really does need a better bearing / front support and the field weakening mapping would need changing to get the Higher RPM. It also would have a lot lower power output at the Higher RPM. They really are what they are, and anything significant would take a lot of rework to achieve it.

      2024 Hisun Sector 550 gear sector binding
      By Ductking1
      I recently purchased a 2024 Hisun 550 Sector from Kreps Service Station and am having issues with the gear selector, I am doing as instructed in the owners manual but the shifter acts like it is binding or the button lock isn't releasing, the shifter will not move, I have to wiggle it back and forth while pushing hard on the brake and if it's in park or reverse it's nearly impossible to get it to move, I contacted Justin Krep and he says this is normal with these machines, I find that hard to believe, I've owned many utvs and side x sides and have never had this kind of issue with any of them, any help with this problem would be greatly appreciated.

      2017 Cub Cadet Challenger 750 hisun junk motor
      By hisun junk
      As I tried to do a conversion with the Yamaha 660 motor, I realized the 660 was never fuel injected so it would not work for the fuel injected hisun motor swap. But the good thing is the hisun 750 motor is a clone of the 660 Yamaha but with the components for the fuel injection (cam/crank position sensor). So that left me with a new rebuilt Yamaha 660 and still a broke 750 hisun motor. I took apart 750 think the timing chain had broke from all that I've heard about these motors. The chain was not broke, but just off cam and crank gears! The chain tensioner was at fault!  I've ordered Yamaha 660 replacement parts, chain, two exhaust valves (which got bent when chain came off while motor was spinning) and seals. The piston has 2 little nicks where it had hit valves but no damage otherwise. The head is being redone at the machine shop and I'll be putting it back together in the next couple of weeks. Also I finally tracked down a Service Manual with all the info on the 550/750 Challenger.

      Hisun Vector E1 - Gear oils
      By Justine
      I've had a Hisun Vector E1 for just a bit longer than is required for me to do some maintenance. While it's well-overdue, it only drives 1.5km a few times each week on a fairly decent gravel road (to the letterbox), and it has worked really well right from the get-go.
      Looking at the manual it states that I need to use SAE80 API GL-4 Hypoid Gear Oil for the Main gear Case, and SAE80 API GL-5 Hypoid Gear Oil for the Front gear Case - unfortunately i can't find either of those online here in Australia. Plenty of options that look close, but, as someone who has never driven any vehicle before, I want to use the right thing and it's a tad confusing.
      My question: Since there are no oils that are bang on SAE80 (they all seem to cover a range) would Liqui Moly Hypoid GL4 Gear Oil 80W-90  & Motorex Hypoid GL-5 Gear Oil 80W90 - be ok to use? (Or any other suggestions of what I might be able to purchase online in Australia) And would I have to drain out any existing oil from both gear cases?
      This is a whole new world for me and  being able to find exactly what is specified in the manual hasn't made this easy!

      2022 Hisun Sector 550 eps. Power steering not working
      By A P
      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.

      2021 Hisun Axis 500 No Start - Need Help Please
      By Hunterman22
      2021 Hisun Axis 500 UTV (From Lowes)
      Will NOT START
      MY apologies if this is to much info just wanted to give yal the most information possible for help.
      I'm a so called diyer. An Electrician by trade 21yrs. I got my S×S from my last job. The contractor purchased this S×S for this specific job brand new, from Lowes. They used it for hauling materials, tools, & a little bit of anything you can think of on an Industrial type job site. 
      I remember getting on the SxS one time & pushed the gas petal all the way to the floor & SxS had very little power. 
      So anyway ,when the job finished up back mid July this year (7/2024) , I asked the contractor what they was going to do with it. I was told to take it. Otherwise it would go to the contractors yard (storage yard) & most likely rust away. 
      Took it home washed it , it had a heavy coat of dust on it & in it dust was every where. My helper & I had to push it on the trailer to get it home.  After washing it throughly I let it sit & dry out for a good day and half, maybe 2 days. Before trying to start it. NO START. Will turn over & try to start but thats it. 
      So here's what I've purchased & installed. New Air Filter, new spark plug, new air idle control valve (AICV), new throttle position sensor, new throttle body, new oxygen sensor, new digital dash speedometer/fuel gauge/clock. 
      Also drained the old oil & gas & replaced with new oil & 93oct. gas. I should probably mention that I've changed the AICV twice. The 1st time I changed the AICV I was able to get the SxS started & let idle for at least 10-15min. Drove out of the garage, with very little power,  turned it around & barely got it back in the garage.That was the one & only time I've been able to start the SxS. I've also cleaned the Throttle Body and & intake with TB cleaner.  So after that the AICV was  making weird noise so I pulled it out & tried cleaning it, pretty sure I messed it up. So I purchased a Throttle Body that came with new AICV & TPS. Still NO START.  I've checked the fuel pump & the fuel injector.  I took the injector off still hooked up to wiring & turned the key over, the injector sprayed a lot of gas out kinda the size of a volleyball. I've also checked the clearance gap on the intake & exhaust valve. But today 11/2/2024 I'm going recheck spark plug gap & the valve gaps. And alot of other checking. Would the driver side seat belt have anything to do with it not starting?? I know the driver side seat belt has to be in gauged for full throttle "going fast". Thing is the drv. side seat belt will latch but feels like might be messed up inside of it. Tired opening it up but to no avail.  I've never had a S×S or 4wheeler so I was really excited when I got the S×S,not so much anymore.  I work on & fix my own vehicles usually no problems.  But this SxS is kicking my ass.
      So if possible & someone could help me with some ideas or tell me what Im doing wrong or did wrong, I would greatly appreciate it.  Thank you for reading thus far.
