I’ve got a Hisun 750 that will all of a sudden just shut down, like it lost all power. Once it sets for a while it will start working again. Put it not getting hot so I’m having trouble trying to figure out what’s wrong with it. Does anyone know what it it?

Mine (HS800utv) did that sort of things few weeks ago.  After intense testing I found the voltage regulator was fried so my battery was not able to charge up.  Replaced it and all works now.  It's located near the battery on mine.  Worth looking at it see if you get good voltage coming in and coming out of it.  Mine was taking the voltage in but the out was fried/melted.

I am having a similar issue with my Hisun 700 it boggs out to almost the point of dying then it recovers then it boggs and has trouble idling. I have cleaned the fuel system and tank and replaced the fuel injector I put an inline filter on it and a new coil wire. Also the plug is really wet when it dies and willl not start back up. It will also smoke a little out of the exhaust. Where should I look at next? the fuel pump seems to be working ok as the see thru fuel filter stays full of fuel. Any help or suggestions would be really really appreciated.

I had this issue just a few weeks ago. I could also tell if I listened real close a change in idle when messing with wires. I ended up finding a soder joint between to voltage regulator and the engine from someone installing a aftermarket stator before I ownedit. It would run fine till the engine got nice and warm then die till it cooled off just a little. I would check around this parts and area. I hope this helps!

Thank you Fib103182,

I will look into that this evening. I pulled the injector again and tried to test it but could not keep the feeder  line seated well enough with my hand so that fuel did not leak out. I was also told to inspect the exhaust system so I pulled the header pipe and the muffler but all seems well.  I figure your right after doing so much with the fuel system it has to be something electric. I really appreciate the advice I will let you know how it goes.

      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.

      We have a 2018 Cub Cadet Challenger 400 and I found this Internally Threaded Bolt with a 10mm head size laying in the floor of the shop bay here on our ranch where we park the Cub Cadet.
      Trying to figure out where it belongs...

      Is the cam sprocket a bolt removal or is it pressed on? Dang bolt is on tight. Impact wrench won't even move it.

      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.

      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!
