The other thing is I bet the value of TCI pickups and stators is on the rise.
I checked the resistance across the pickup taps inside the GN box the other day. Don't recall exact... but it was somewhere north of 5 megs, so we need to tread lightly closing that loop. Could easily drown out the signal we want to keep.That is my thoughts on the issue. I think the advance coil floating from ground is creating noise on the idle pickup that the box adjusts itself to. Working on a connection to the advanced coil that will shunt the unwanted signals to ground.
I'm with you Jim, really looking forward to see the timing video on more bikes to quantify the results. The resistor is more of a chicken soup thing .I'm thinking more bikes running for comparison before we try to fix a problem that might or might not exist. Rudy ( @azman857 ) , can you put up a video of your bike on startup with a timing light on it?
Bubba method of finding sensor placement. just need the distance of the purple segment.

To clarify that statement is not exactly true. The Gonzo fires on the start of the negative side of the pulse. I think most of these boxes fire on the transition from positive to negative which happens as the magnet passes the center of the armature, (the red dots). Makes sense because if it triggered on the start of the positive then variations in the magnetic field(size of magnet,strength of the magnet with age, pickup flying height etc.) would influence the spot where it fires.The yellow line should be on the leading edge of the pickup.It's the lead edge that sets the timing.

The holes for the pickup will not be in the stock location.
The holes in the new pickup will need to be slotted to allow for adjustment.
Edit for my diagrams relating to the yellow line..........The pickup should be on the edge of the yellow line and placed back towards the Blue lineI was just trying to keep it bubba simple. No degree wheel, trying to find the center of the window of the stator where the screws would be etc.. It is simple to lay a straight edge over the window and measure to where the center of the pickup should fall. Kinda like Jim's trick for finding the magnet position
A couple of notes

I hear the toilets swirl opposite also.
