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

Ive searched and cannot find any performance parts that fit my machine.
I have a 2020 coleman ut400.
Im looking for machined sheave kit, programmers, cdi, exhaust and intake.
I know these are yamaha rhino clones but are they rhino 450 clones?
Any info is appreciated.

Have an issue all the sudden where the UTV will cut out randomly mid range throttle and under load. Light consistent throttle on fairly flat ground no problems. If you quickly change throttle position sometimes it will bog down and cut out, splutter, etc. Floor it or let off and it may do just fine. Going up a hill and adding more throttle as the incline demands, will cut out splutter and smell unburnt fuel. So far doesn't ever completely quit. If you let off it will idle just fine. A lot of times if you floor it, it will pick up and even get a boost of power. Changed to a slightly hotter plug to see if that would make a difference, but it didn't . Any ideas what might be going on and what to try next?

I'm looking to purchase a 2015 Massimo 550 that might have an issue with it's throttle position sensor.
From the fella selling this UTV, he claims its to set the idle on fuel injection because the engine will not stay idle or when it starts sometimes it idles too high.
My Question if anyone had any issues with their Massimo 550 and if it was actually the TPS or something else that would allow the machine to idle correctly.
Thanks!
