Solved. New plug wires and problem is gone.
Even though wires on there passed all resistance tests and POSplayer's "sparks and magic" night test, obviously they were still bad (well, bad in the sense that although bike ran fine, there was serious voltage leaking everywhere).
Why? Who knows and I don't even care anymore. Took me most of the afternoon to put the bike all back together (I took my time and cleaned more things up), but I'm just happy it's finally over. Talk about feeling like an idiot though

I could have thrown the $20 wires on there a month ago an avoided a TON of headache (for me and all of you). Arggh.
I want to thank all of you who chimed in with advice to help me.
For what it's worth, in case POS and Redman and Steve are curious:
* All tests (except coil resistance) were performed with bike running
* All in garage, both my bike and Shiraz's, no fluorescent lights
* Disconnecting battery positive with bike running kills bike (as with all bike wired for points, whether changed to electronic ignition like mine or not)
* Points replaced long ago by Dyna S (check my signature block Mr CaveHamster)
* Redman- good luck in job search. I'm in the exact same boat. Sucks rocks.
But hey, gives me time to sort out the old bike finally. I eliminated the stator and RR as potential contributers by totally removing from bike and still got crazy fluctuations (earlier in post, sorry....i thought I reiterated that)
* Not the meters (Steve summed it up below...we tested that to death)
I love how the thing fires right up NOW with the coil mod. Test ride tomorrow.
