Hey Aelius. I really can't add anything as i'm a newbie myself, but just want to ask, do you have a tachometer?
I think i'm suffering the same problems as some others here (Not really got used to the volume of the engine when the revs are up), but it never used to bother me on my old bike. Basically, I have been questioning myself over why i'm so bothered and come to the conclusion that it may be that I can't see how many revs i'm doing, so i'm too cautious of holding te revs high over longer periods of time (They may not even be that high you see, I just might *think* they are because of the noise, and no tachometer). So err, just wondering
