So, wanted to wrap up this thread. Kudos to Ruan from Hex, he was very responsive and great to deal with. Turns out there is basically no damping present, either compression or rebound, when the bike is idling. It will pogo up and down freely. Once underway the damping kicks in. Was on a ride with some friends and one of the guys had a 2018 GS1200 with ESA so we started his bike in neutral and it did the same thing as mine, so apparently this is intentional, no idea why.
On another note, on my 2021, when I one of my four enable ride modes includes and Enduro function, there are three damping modes, Road, Dynamic and Enduro available not just two, so a little bit of good came out of this exercise.
I wish someone built software that would allow adjustment of the basic rebound and comp setting instead of having to buy an entire new shock. Sigh
