Same here playing with the settings.
My rear shock is now on the last to highest notch for spring tension, with the damping adjuster screwed all the way in and backed off 1/8 turn. This works pretty well on my local bumpy roads, but means I'll have to play some more with the front (again).
The front seems to dive with the slightest whiff of front brake, but at least the pogo effect has been dialed out. Progressive springs for £80ish might just be the cheapest option to make the bike 80% where I would like it to be.
There is no way I'll be sending £1000's on getting it perfect.
Has anyone considered looking at this from a 'fit for purpose' angle? Never mind going to the bike stealers or importers, take it straight to 'Trading Standards' or whatever your regulatory authority is, also to whatever national government bodies there are and report them. I'm sure that some will have seen the penalty applied to Toyota in the USA and that seems to be only related to floor mats interfering with the accelerators!
You should not have to spend 1000's on improving a -product if you are using it for the intended purpose.
I don't advocate spurious claims without a sensible basis, but as 99% of those commenting are so far removed from a Valentino Rossi or Bradley Smith, even in their wildest imagination, it makes it simply a fit for purpose issue.
