Since you've already changed the coils and plates with the same results, you might want to check the rotor; a bent advancer bolt might be causing too large a gap with the 2-3 pick-up?

That's cruel....but probably true.

Trey if your Dyna s is toast consider a pamco as another inexpensive hall effect ignition option.
Or points....
Got rid of that air shifter yet..?

I DID NOT fabricate those air shifter brackets for that big air shift cylinder you were using, so I'm not surprised it was in a bind. Now get rid of that damn big air cylinder and get a small one. Please!!!

Trey, if it shifts fine with your foot and don't pop out of gear, it's probably your air shifter that is not set up properly.

Sound familiar Frank? ;)

I noticed on the last pass that it failed that it still had around 100psi in the tank and still managed to slip into false neutral.

I put 140 in and ran again and all 5 gears pulled no problem. Cant seem to figure out what caused that failure. It happened earlier in the day as well.

I probably just need to get the MPS switch and go Electric/air and see if it helps..

A loose chain or one too tight with an air shifter isn't a good combination either. Be sure its adjusted properly. After having trouble with mine not shifting and replacing a lot of internal and external components, I ended up replacing the air kill with an MPS electronic box with adjustable kill time. That did seem to solve the problem. Glad i had that box laying around from another bike.
I can't find the original thread, but I know we've had the same discussion about air shifters before, Frank.

Yeap. I haven't forgotten.  I adjusted the kill time. Its not popping out of gear.
