The other issue I'm having is if it's been sitting in the sun for a while (texas heat), when I crank it up, it gets into a weird rich->lean->rich oscillation for a few minutes before smoothing out again.
I think I have a few logs of both cases if someone wants to take a gander at them.

Everything you mention above I lived with for months with the single O2 sensor set up. I had three bikes: a morning bike, a noon bike and an evening bike: the tuning changed three times a day on the same day on the same bike. Seems like 11 A.M. would do the trick as well as 8 P.M.. So, I named my bike "Maybe - Maybe Not." Would it start, would it idle, what time of day was it? I wish I could tell you in 20 words or less how "it got fixed." All I can say is be aggressive with the alpha N at the top horizontal row, save each change and when you get close, take a break and go for a putt. Then in a day or two refine it until you get closer and closer.
Finally, if you are worried about heat issues if you have to lean your bike out, look hard at the Advance timing since if it is too low, you get more heat generated. I easily took 15C degees out of my ET with better advance. Since my engine is not a race engine which will be rebuilt after 100 runs or so, I don't take the advance to the rattle point and back it off. Close is good enough for me: good fuel consumption numbers, no decel popping, 115 to 120degee C ET, no knock and decent performance tells me it is close to spot on for an enthusiast and reliable riding. I just hope it stays that way......... .
