Okay everyone, need some help here. I got my 2014 Bennche Bighorn 700 from my father inlaw. He has had it since new and as far as I know never had any problems with it until recently. It began with it being hard to start and having to give it some throttle for it to start up. Then it wouldn't stay running once it did start. If you go to start it, it will fire right off and only run for a split second and then die. If you give it some throttle it will start and stay running as long as your foot is on the pedal. While it's running its pretty rough and backfires. Here is a list of everything I've done so far. Initially I checked compression and it was low. I changed the cylinder, piston and rings. Took the head apart cleaned and laped the valves. Checked timing a few times. Adjusted the valves. New spark plug. Checked the air filter, it was fine. New battery. Changed the fuel pump because of a broken fitting. Changed the fuel filter, lines and fuel injector. Dumped the old fuel and put new in. Changed the air idle control, TPS, MAP sensor, Voltage Regulator, ECU and harness. I was getting codes 31, 107, 113 and 122 on the display. Once I changed the ECU no more codes have been displayed but still have the same issues. All fuses look good and as far as I can tell Grounds are good unless there are some I can't find. I'm at a loss here. Not really sure where to go. Compression was better after everything I did but I don't remember the numbers. I'll have to check it again if someone thinks that could be the issue. Any help would be greatly appreciated!

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.

Hello I am new here but have had this machine for about 5 years. I am having issues with it surging and sometimes sounding like a small backfire thru the intake. When putting in low, high or reverse it will struggle then go full power then struggle. It will only do the small backfire thing while in neutral reving it many times. Once in awhile it will throw a check engine light.
Parts replaced/checked:
I have checked the valve lashing, timing and adjusted. Parts replaced are the coils, spark plugs, injectors, fuel lines, fuel pump, IAC sensor, TPS sensor, throttle cable, speed sensor, primary and secondary clutch and belt.
