My '07 F4-1000R was a serious under-steerer when I got it - riding through a car-park was an exercise session. Finally, one evening, I noticed that the main-beam was pointing way above horizontal. By adjusting the rear ride-height up to lower the main-beam onto the road, the steering heaviness went completely away, and the bike became very balanced.Wow, if you like the way it rides now, wait until the geometry is correct.
Did they also drop the front by Raising the girls or doing internal fork mods?
Where are you located? Some of us have the tool to loan out.

Find the section on ride height adjustment. Mine was low only about 10mm and I hated the steering feel, I can't imagine how bad 2" down would feel
