Actually, when I ride with my wife/luggage the bike is quite stable: the problem is when I have only the luggage. Do you have a similar experience?
PS: funny, I have almost same pressure as you, but reversed: lower on the front. I've seen that high pressure at front tire reduces stability, although now I'm curious to try it again.

Nope, in fact, I was solo, with side bags, during a 413 miles on a trip to Monterrey, from Reno see map; and flogged the hell out of the PP. No probs whatsoever! Gotta be your suspension setting. An example of your bike instability?

It sounds like your rear preload is probably set too high (or your front is too low) if it handles better with a passenger than without.

I'm assuming that you set the preload to 2 riders when you are riding 2 up, and 1 rider when you are riding alone? Go through the menu and see what the 2 rider preload is set for (1 - 24), and what preload the single rider is set up for (1-24).

I'm 210 lbs with gear and have measured the front and rear sag with just me on the bike, and then with my wife on the back. I ended up with a preload of 14 when I'm alone on the bike (33% of full travel sag), and a preload of 24 with my wife on the back (33% sag). In order to achieve a sag of approx 33% on the front, I had to crank the preload all the way in (clockwise), and then backed it out 3 turns.

Cheers!

I feel the same! Whenever I do changes on the bike I am very careful, it's so easy to mess it up....

If I bring this forward, for sure I will share the outcome!

It's something that happens only at speed higher than 100 mph: the faster the worse. And of course it gets worse with the load on the panniers and if I put the top case.
As soon as try to change direction, the bike starts waving: it's an oscillation that involves the front wheel but the rest of the bike follows.
It's not at high frequency like when you are leaning and give gas, and the front starts oscillating.
Depending on the conditions, up to a certain speed this can be controlled and after some time the bike is stable again. But if I'm too fast, or I have too much load, the oscillation tends to increase instead of reducing.

I actually did some tests changing the preload. But after reading your post I'm having some doubts: I gonna do them again
