I have replaced the ignition coil, spark plug, injector, fuel filter, map sensor, iac sensor, checked fuel pump and it still acts like it wants to cut out when my revs are over 3100 rpms. the problem is intermittent but happens frequently and i dont want to leave my hisun at a dealer 100 miles away and wait months. It never stalls but it idles rough and sometimes when its real bad i cant go over 10 mph. yes i fasten seat belts

I have an issue and I'm hoping that someone can help with a little Wisdom. I have a 2016 Massimo MSU500 UTV that blew a time chain while out riding. It has been torn down to replave the chain and Sprocket amount other things that will be renewed. The problem comes in with setting Top Dead Center on the motor. The Manuals all teel one to line up hash marks on the flywheel with a point on the side cover under what's referred to in several place as a manhole cover. Its a large headed cap/bolt that unscrews and allows you to view the edge of the flywheel. There are hash marks on the flywheel that your supposed to turn the crank until you get the proper alignment between a certain hash mark and a reference point on the Case. Problem is there is NO reference point on the case there. I also have another 2016 MSU500 and a 2014 Coleman 500. Not one of these machines have a reference mark of any kind in that location. (I have pictures if needed)
I know I can use the old pull the valve covers and rotate the crank and rely on getting the right point where Both Intake and Exhaust valves are closed at hopefully the correct point in the piston stroke. Is there any other reference point that could be used for this or is this the only thing left to use for finding TDC? Gotta Love documentation that doesn't match the equipment it's supposed to be for, any help would be greatly appreciated. Even if just to tell me that's about my only option.
Thanks to all who even take the time to read my rambling question.

Hey Guys, I have been chasing a stalling condition for about two weeks now. The bike will crank up and idle fine, then after about 20 seconds it will fall on its face and stall. It happens at both idle and while running at various rpms. You can turn the key off, turn it back on and it will fire right back up without trouble. I have verified spark on both cylinders with a spark tester. I have also added an inline fuel filter, and pulled the injectors to verify proper pulse on each. Things I have replaced - (relearn procedure performed after each component replaced): spark plugs, ECU, relay/fuse box, fuel pump, & throttle position sensor - all with no improvement of the condition. The only warning light I get when the condition occurs is the oil lamp. The bike only has 14 miles. I am at a loss and appreciate any help and suggestions! Thanks

My intimidator EV is dead, no lights when ignition is turned on. All batteries test good. Any ideas where to start looking?

I have a 2020 axis 500 and I have replaced the TPS twice and the whole throttle body assembly once and still have code 122. I can barely drive the thing. It bucks and surges like crazy
