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

I started my UT400 but forgot to buckel my seat belt. It bogged down and then died. Only way I could restart it was to press the gas pedal and if I let up on it, it stalls. Any suggestions? Thanks.

Recently I had an overheating issue on my 2022 Coleman Outfitter 550 (Hisun UT550) and to check to make sure it was fixed I took it out for a ride around the block. After a couple cycles on the LED coolant meter, I took it for a couple mile ride and on my way back I heard a loud metallic snap then a grinding noise. It was still able to move under its own power but very slowly. I was about 2 blocks from the truck so 'I limped it home and up onto the trailer. I know I need to tear it apart and look for what broke, but anyone have a guess as to where to start? I'm seriously getting tired of this damn machine! 750 miles on it and already replaced the belt, wet clutch, primary clutch, clutch roller weights among a few other things. Seriously, this friggin machine has spent more time on the lift than on the road. I thought I bought this new because it was from the owner of a tractor supply, but he registered it under the stores name making me the 2nd owner voiding any and all warranties.
Any Ideas what to look for would be appreciated.
Thanks
