I raced 2006 675 for 2 seasons and loved it when I got the geometry and suspension sorted. I just bought a 2014 675R for the road and track days and think it's a vast improvement stock although I'm still running it in. I did work at a suspension tuning shop with one of the world's best so I really had an advantage (he's also a 5 time national champion and raced wild card 250cc grand prix in the early nineties).
I found it was extremely sensitive to front / rear ride heights. Even a mm difference made a huge difference. You're on the right track raising the forks. I would also take a link out the chain and get that wheelbase as short as possible (massive difference and able to hold a really tight line).
Also, and this applies to all bikes, get some light fork springs in the front (9kg) and really soften the front compression. It gives you that feel that you're after and you can carry huge speed in the turns and hold a tight line. Don't try and control fork dive on the brakes with hard springs and compression, control that with air gap.
I was given a brand new 2008 R6 to race and gave it back after one session on the track, the triumph was too good out the turns with its torque and corner speed was immense.
