I have a hisun 700 I went out to start it one morning and it made a clunk then nothing I am  mechanical inclined so I start trying to figure things out.  I narrowed it down to starter.  I changed it out with a brand new starter it made a grinding sound then nothing please advise me as I’m a old points and spark plug kind of guy not much experience with utv point me in the right direction don’t want to start tearing things down that don’t help??

Are you sure there's enough voltage at the starter? A clunk sounds like the starter bendix has engaged, but nothing more. That could be a bad starter, or a cable not delivering enough power. I'd also make sure the negative cable has good contact. 

Is there any corrosion in or on the cables? I'd test for voltage drop in the cables. Since you're replacing the starter, it should be easy to get to the cable for testing. 

Probably nothing, but it's a good idea to check it occasionally. Since it's possible for a cable to look perfectly fine. While having corrosion inside. It's a simple test, usually done with a multi meter.

Okay y’all I have checked the starter new one and the old one both work I found a online video showed me how to test.  There both find I get 12 volts with the key on through the cables still won’t turn over any suggestions

If you have any reason to suspect that flywheel is the problem. Then it will need a proper inspection. That cover needs to be removed. The only thing that you can really check through the starter hole, is for missing flywheel teeth. 

And even that is easier with the shroud removed. However, the missing teeth, if that's the problem here, would most likely be right there where the flywheel is presently indexed. And should be easily seen through the starter hole. That's why I asked if you have any basis for the flywheel being the problem. 

Removing the spark plugs will allow you to rotate the engine. Allowing for flywheel inspection.

Thank you! I know what I’ll be doing tomorrow. I hope it’s nothing but if the flywheel doesn’t move it’s got to be something else I’m hoping it just the fly wheel  thank you for your support and knowledge

Not to scare you but I had a somewhat similar issue and it was a broken valve.....in the middle of re-building the top end right now.

I would remove the fan shroud and see if you can manually turn the engine over with a socket....I could not crank over by hand.

Tore it apart and found a broken valve

Hi my hisun 700 will not turn over seems dead. If you look buy your battery there should be a30amp fuse  try moving it around check wires going to it.  Fixes mine every time. When this fuse shorts out loses connection  your  dash will not start working.  Mine is a 2009 700 . Not sure what year you have or if has been changed on newer models.

Yeah, it could easily be an obstruction from a broken part,  jamming the whole works. I've got my suspicions about what's coming. But we won't know till we hear back from the op.

      I just bought a new 2024 Hison 550 Stryker 2 months ago. this is the second time I have had this issue.  It only has about 20 hours on it. The last time it happened we took it back to the dealer. it was a fuse.  Since we live three-hour time driving there and back. I would like to find another solution if possible.  I have tried all the fuses that seem to have anything to do with starting.  Currently checking the battery. The battery is new. it came with the unit. It is probably 6 months old.  the UTV has all power to everything electrical. lights turn signals and radio all work.  When trying the key to start . it is 100% dead. as in it doesn't even click.  There is a low whirring like the fuel pump is turning on though. The Unit was running and driving just fine.  we shut it down for the night. The next morning my wife found it in this condition.  Thanks for any Ideas or solutions???   Otherwise, it goes back to the dealer tomorrow. Just hope I didn't buy a lemon. Great little UTV when it does run.😅  anyone else ever have this Issue..?

      I turned off the key and then tried to start it a minute later and it would not start. I changed out the fuel filter and the injector. still nothing. if i have the injector pulled out and close to the hole the injector will spray fuel into the hole and it will run but the minute you put the injector in it will die. any idea's please

      2018 Massimo 700 MSU. The machine started burning oil all of a sudden. One day fine-- next morning burning oil. Looking for advice. Do I pull the engine to inspect the top end or can it be done with the engine in place? Pro? Cons?
      Any and all assistance is greatly appreciated in advance.

      I have a 2013 Hisun with a 686 Yamaha engine.
      I purchased it from an individual and it ran fine as long as the battery was full.
      I replaced the stator and now it will not start (run).  It cranks fine, has fuel pressure, but will not fire up.  I replaced the coil, no luck there.
      a technician told me that it was the wrong stator and wants a mint to replace it.
      the wires all plugged in when I installed the stator.

      This mod is not for the fainthearted, as it requires some basic metal fabrication and welding skills.  But the result is worth the effort IMO.  I chose an aftermarket Honda Talon windshield based on economy, size, and construction (aluminum frame, DOT glass, folding, windshield).  It fits OK, a little narrow at the top, and you need to incorporate the lower section of the original acrylic windshield and build some additional plates, but better than being too wide.  If you are wondering why I attacked this mod, it's because mine is driven daily on the street.  Tired of fading, scratchy, hazy plastic.  Sucks in the rain; sucks at night.  Now I can see.
