Those are the first thing I checked. I basically ripped out a perfectly good ignition and coils.

It's hard to say. I have a CV instead of a S&S, but mine idles lower until warmed up. Once warmed up the idle smooths out and increases.

42 main jet today. Bike runs like a rocket over 2k rpm.
Carb problems would not make only 1 cyl miss.?

Making a video & posting it on youtube is a pain.
Yep misses at idle and smoothes out about 1500 or so.

Does the exhaust pop on decel? Does the carb spit or backfire? Just making sure you eliminated an exhaust leak.
I know you checked for an intake leak with carb cleaner, but what you describe sounds like an intake manifold leak. I would check, or maybe just replace gaskets, and check condition of manifold. Good luck.
