Hisun 700 No Start Help

[Farm man 0]

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??

If you have the old starter still, I would compare and count the teeth on the starter gear old VS new starter.

Thank you I will check

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.

Thank you I plan on working on it today I will perform voltage test  and inspect cables

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

The starter just doesn’t turn the fly wheel?.

[Travis 212]

Check the battery voltage, key off,everything off., Then have some one turn the key to start and hold it there while you're checking the battery if the voltage drops to about 10, or 9 Volts, I would  replace the  battery.

[Travis 212]

Or remove the battery and have a parts store load test it.

Have you tried jumper cables?

[Farm man 0]

Yes

@kenfain I’m thing fly wheel?

[kenfain 174]

Why do you suspect the flywheel? Has it been damaged?

[kenfain 174]

Have you tried to manually move the flywheel? Is it loose? 

[Farm man 0]

@kenfain no there has been no damage I don’t know how to check flywheel without taking the plastic shroud off do you other than going in the starter hole

[kenfain 174]

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 

[kenfain 174]

Keep us posted on any progress. Good luck!

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
