This is an interesting read. ADAS is main stream on cars these days. The technology looks to be headed towards UTVs and Off-Road Vehicles.
Potential Motors and CFMOTO USA have announced a new partnership to integrate advanced driver-assist systems (ADAS) into recreational off-road vehicles for the first time.
Sam Poirier, CEO and co-founder at Potential Motors, says the integration of its technology into CFMOTO’s vehicles will set new standards in the side-by-side segment. (Photo: Potential Motors Inc.) The partnership will first see Potential’s tech integrated into CFMOTO test vehicles. The companies will conduct extensive real-world testing at Potential’s purpose-built off-road proving ground in Fredericton, Canada, and CFMOTO facilities.

2016, Hisun 500 turns over great but Spark plug is firing when I turn the ignition key on. I’ve got good fuel pressure to the injector. Pulled plug out and it is wet with. gasoline. Air filter is clean. Turns over great just does not even try to pop or start.. I’ve checked off uses and they are good when I turn the key on I’m getting power to the injector.. I’m not hearing the injector pulsing, but may just be my hearing.. With the spark plug getting wet with gas I feel like the injector is pulsing and spraying. Any suggestions would be great. I don’t know the hours on the unit offhand, but it has 600 miles on it. Thank you for your comments and advanced.

Bought a used 4x4, engine runs. Tried rebuilding both pulleys. Ended up buying a transmission pulley system. The new one is aftermarket. The old one wallowed out and fell off.
The new one seems not to have enough splines inside. Seems like it is freewheeling. When it revs up and gets smaller pulley diameter, does it jump on the spline shaft? The driver pulley on the engine gets larger when it revs up. Had to make a pvc collar for the belt to sit on in the grove. No parts for sale on this pulley. Is the belt supposed to sit at the bottom? There must be a trick to get the belt on. Any ideas?
Thanks Dave in Florida

Quick history:
Bought it about a month ago and when I test drove it, it ran good. Loaded it up and took it home. Owner said it had been sitting for a long time, but was "just serviced". It only has 500 miles on it total. Drove it around and found out the charging system wasnt working...so had to charge the battery once every week and a half or so. One day my daughter was driving it and it died. I couldnt get it to start again and I noticed there was no fuel in the filter...I first checked pulse/vacuum line to make sure it was sucking and it was. So I replaced the fuel pump with one I found local...which is for a large riding lawn mower...and it worked. Engine started and ran, but struggled at low speed immediately following running it at higher speed. It would bog when decelerating. I have also noticed now that it will backfire some on decell and die.
In the meantime, I went ahead and installed new stator and trigger coil assembly to get the charging system working again (that was an issue because it would not start at all after that...but eventually found that the trigger coil was wired backwards in the plug from the factory). I have also set valves, but I set them to .005 (intake) and .007 (exhaust)...per the manual. But what is weird is the manual states its mainly for the 700 series, but "can" be used on other models. On the front it says 500/600/700. I have noticed that the most common setting seems to be .005.
Anyways it still has the issue to me that seems like its running lean. Not full power now, struggles immediately running it faster, and will die and pop some on deceleration.
My main problem now is that it wont get to higher rpms as fast as it did when I first bought it. It struggles on deceleration after running near top speed.
Things I have done:
changed fuel pump
replaced stator / pickup coil
thoroughly cleaned carb (twice)
set valves to .005 and .007 (is .007 too loose for exhaust?)
anyways it seems to have a lean problem, and wondering if you have any suggestions on what to check.
Thanks

I have a 2018 cub cadet challenger 750 I bought brand new almost 2 years ago the first month I had it the exhaust broke and burnt the spark plug wire in two that was a recall so the dealership installed the new one it had a different design and it bolted up to the bottom two plugs below the spark plug the dealership said they had to Adjust the exhaust valves I get the machine back thanking everything is good now wrong not even a week after I get it back the timing chain tensioner comes apart inside the motor I take it back to the dealership They put one on I get the machine back thanking everything is good but then just like before not even a week goes by when I was riding the Machine automatically quits going come to find out the wet clutch was burned up the primary clutch head stripped off of the splines I get that fixed and then it overheats I take it back they bleed the air out of the coolant they bring it back to me the same day that I get it back it overheats again I take it back they temporarily fix it again just enough to let the warranty run out and now the machine has been to multiple different mechanics I have had them try to bleed the air out they have stood it up on its end I have had the water pump changed I have had the fan hooked to a switch so I could leave it on all the time but still almost 2 years later not even 200 hours on the machine and I cannot ride it The dealership will not take it back as a lemon I have tried I am at my wits end I have no clue what to try next
