New to owning a UTV and got myself a project one as my first one.
Changed out the clutch and clutch housing etc. as the UTV was having problems going up hills and getting up to speed but now in the process of putting it all back together it won't start. Also changed fan gears for shifter
Here's what I've found so far (apologies for the bullet points);
Motor will crank over and makes good turnover speed. If I use spark plug tester or ground to engine, no spark. At the connector to the ignition coil I get consistent 12v on the white wire and nothing at the black. Read in one of the posts that the 12v to the white wire should be intermittent when trying to get a spark at the plug? Tested ignition coil using a multimeter on resistance setting. Between two pins I get 0.46 ohms or thereabouts. Between either pin and spark plug boot I get somewhere around 16k ohms. Not really found a good video on testing these coils but think those are good readings. Checked fuses in fuse box and are all good. Fuel pump cycles on when I turn key to on position. I disconnected the ignition coil to remove the clutch etc. to get it out the way but don't think I've damaged anything in the process. Can anyone point me in the direction of what to try next? Been trying to use the manual but considering the test procedure for the ignition coil is for the wrong type of coil, it's not been too helpful. I've read on another post about checking the ECM the two pins with 12v etc so will take a look at that next but any ideas that could get this machine started again are welcome!

I have a Hisun Strike 1000 I have been trying to get going, it has only 39 hours on it, so I can only assume it has been sitting for a long time.
The issue is it is losing spark to both coils after 20-30 seconds of running, doesn't matter if it's WOT or Idle, it will shut down. What sends signal to the coils to fire? It has a crank sensor, I was thinking a CDI box, but I have not found one of those on the machine.
The rear end was busted on it when I got it, So I ordered a new one and installed it only to run into this problem. I can only imagine the problem has happened over it sitting so long and not being driven.
I originally thought it was a fuel problem, so I checked the injectors, throttle body, o2 sensors. Discovered the heating element in one of the o2 sensors was bad, so ordered both and also replaced both injectors just to be sure, then discovered it is only losing spark.

Going down a 20 deg hill engine is holding UTV back. Then something releases like going into Neutral and makes a loud clacking noise. Have to use brake to slow UTV down. Then once level it shifts back into gear. Have done shift extension does not pop out of gear.

We just bought a used 2017 American Landmaster TW450. No hour meter that I can find, so not sure exactly how much it has been used.
The first 2 days we had it, the starter was a little sketchy, but it started after 2-3 tries. Sometimes when turning the key, we would hear a loud metal "clink" sound. Like the starter made contact, but didn't have enough power to turn.
THIS MORNING... Turning the key, we hear a single click sound. That's it. Even with a new battery, the starter is still doing the same thing. Both batteries (old and new) were reading 12.8 volts on volt meter. So I'm wondering what else could be going on? Any ideas on what to look for would be greatly appreciated...
Thank you!
