I'm also 6'4" and 220lb, so plenty of people on Dukes are big
Hahaha…I think I need to spend more time on the Peloton and less time on the Ducati lol
look how far I had to tighten down the spring to get 25 mm of sag WITH a 115 nm spring, the heaviest they make lol
How much do you guys think I should have them lower the rear end make up for that?

+1 on the slacker. Ingenious gadget that isJust adjust using the preload nuts on the top of the fork and the preload adjuster on the rear shock. No need to turn the engine on. You will want to disconnect the electronic damping connectors on the forks before you turn the preload nuts. No need to disconnect the electronics on the rear though.
The sag process is pretty easy, you will want 2 people unless you have a digital tool like slacker. I have that tool and it’s awesome since I can read sag without a helper.
Good starting point for sag is 30mm total rear and 35 total front. I run mine lower on the track but this is an ok place to start.
To sag it, you will sit on it, no bouncing at all. This is why you need a second person to measure it if you don’t have an electronic tool.
You sound a like a big unit but bet you aint as big as this guy
What is your static sag with that much preload? You don't want it to be zero. Hitting a bump will bounce you out of the seat.
Unless you are really tearing it up on a track 25mm rear rider sag isn't very much. For street use and beginner track I'd look for that to be 35mm.
Right now I'm 28mm static and 40mm rider front with 12mm static and 35mm rider rear.
Also there is theory and practice, but once you set it up get your notebook out and write down everything, sag, clicks, your weight, fork height, tire pressures, gearing, possibly swing arm angle, ambient temp, etc etc go for a ride see how it feels, note your natural pace. What you are looking for initially is a baseline where the bike feels ok, if something does not feel right dont change multiple things- only one thing. Then go for a ride, take notes rinse and repeat. Eventually you'll get to a place where for your unique style and conditions there will be a sweet spot or the baseline you can always go back to if get lost. Plenty of advice on here on how to tune it but its really important to have a process since there are so many variables
that might be getting used to it, previously with the rear squatting it may have given a feeling of stability. Everything is a tradeoff, the faster you go the harder it is to turn so if you set the bike up to be on rails its not going to turn as well. Try loosening your grip or take a note of how youre riding. I had a problem for a with high speed tank slappers on a certain kink, I was tensing up, but as soon as I relaxed my vice grip hand the problem disappeared.
