The 60psi is most likely you have the wrong type of compression tester. Not suitable for bikes.So any idea why at take off it bug out (misfire) almost imposible to take off and now even more questions why it have 60 psi on all 4 cylinder but ones it pass 4k rpm it have lot of power like new?
The video sounds like a misfire, could be coils or injectors related. I'm leaning towards coils,
because you said it misfires under load and when hot. You said that you replaced all the coils. Were they new items?
Edit: ( I see you started another thread, so I will go there).
