What you are doing is the same I did when I moved from my ZX600R to my CB900 Hornet, I moved because I was fed up after 4 years off revving the tits of it and hitting the limiters all the time.
Problems was I actually ended up riding the CB900 the same, reving the tits off it and hitting the limiters. Its just that you get there quicker and the revs are lower so bigger grin. I always felt the 900 had enough power adn was a great alrounder, I wish that I was moving onto the 1000 from the 900 and not from having the 2 offs, I don't think there would be to much in it from the performance of my 900 as I had geared it and sorted the cans and powercommander so it was pretty nippy. But the 1000 is that next stage on and from what you say about the exhursts 8bhp is easily released which will give that little extra for those that want it.
What you need to remember is that you are probabley riding it like you did the 600 but because its smoother and does things with less stress it may seem as if its slower but in actual fact you are going quicker... Thats the advantage of Torque....
