So I've been back and forth with why my bike keeps fouling a plug in cylinder 4. Intermittent firing and real poor performance. Motor would shut down while in 4th gear. Sketchy clutch at start, super jumpy. Black inside exhaust pipe. Started at the spark plugs then went to clean each of the fuel injectors and then tested ignition coils all reading with proper ohms. Then I pulled this out from under my seat. I have one question. Can my bike start up and act like it's been with an ECU that looks like this? Please notice the photo i've uploaded. If so, I don't know what else it could be. Thanks for any input. It's been a journey and I'd love to just get back to riding...So we're clear, I bought this bike from someone without going over it..

. Can my bike start up and act like it's been with an ECU that looks like this? Yes. Its very possible and likely the ecu, the wiring going into the harness or the harness molding between the terminals that is bad from the looks of it and the symptoms you mention.
It looks like the heat that damaged the case (maybe more) was from outside, so I would get that fixed as well.
