Ok, I installed I/S springs, re-jetted to 38 lows and 115 mains, new F/P pins 1&2 on slot 3 and 3-6 on slot 2, pilots set to 3.5, New K&N without prefilter and sync'ed the carbs.
as noted here:

I felt she was running leaner than she should have been.
Checking out the plugs more or less supported that theory.
When I took her down, I found that an air box mod had been done, K&N air filter with pre filter installed, and the pilot jets settings were anywhere between 1 and almost three turns out. Plus she has a set of Cobra 6-6.
First impressions. (before the sleet hit)
Low end does not seem that great
Upper end: Oh yeah.

When the weather breaks and my forehead thaws a bit, I will some miles on her and
relate what the butt-dyno feels.
Did notice that she no longer pops on deceleration.
