2019 Yamaha Sidewinder running bad!

OK. Coils are good and wiring to connector is good. Since you said you tried new plugs, I would deduce ignition is not the issue.
I've not seen a sled idle w 13.7 volts. Is battery good? Load test?
So next I'd test fuel injector. Spec is 86.4 - 105.6 ohms across the two terminals.
Have you done a compression test?
12.4ohms across each injector and nope only have done a leak down test
 
You mentioned you upgraded your fuel pump, have you tested your fuel pressure?
 
Verify fuel pressure , those gauges are known to be out to lunch
 
We chased a weird misfire and it ended up being the gap 3 bar sensor, your miss might be more specific though. We had another sensor to try which made diagnosis super simple though.

Tried new 3 bar it didn’t help
 
If you haven't already, put the OEM coils back in.
 
Ok. Manual is wrong. Wouldn't be first time.
