It would seem that is a #4 bad coil. It tests fine with a meter. Book calls for 4.8-7.2K ohms and it tests at 7.0k ohms but is missing on the screen as you pointed out.
Dynamic testing is where it's at!

I switched cylinder 4 coil with cylinder 3 and the problem transferred!
Cool! How about showing us that capture.

I would say that proves that the coil that appears to be good with the meter is proven bad with the scope wouldn't you guys agree?
Sure does about 99%

I am pretty confident with this diagnosis.
As well you should be. You pretty much proved it.

I am also confident that this would not have been found without the Pico.
You may have found it without it after how many hours of trying an educated guess from the gut. Changing a bunch of parts that may not of been needed... Adjusting a bunch of setting that didn't really need to be adjusted and who knows the wear and tear on the dyno and bike with the tests that came up empty. Add to that all the hours that netted no income and the stress that come with that. And how about the hours of work that didn't get done chasing this issue down...
I'd say you made a good investment. Even better was the great idea of where you bought it which put you on here with all us other nut cases!

Glad to hear you got it figured out.
