I don't know if it's just me, but this season I have noticed that my GS seems to be running smoother and better this year. It seems to cruise along happily at higher speeds, it accelerates quicker and generally seems happier on the road. I know that this is very subjective and it could be my perceptions that are way off here, but it really seems to me that the bike has loosened up and is, for want of a better word, happier now. It is a standard F model from '09, has done 20K km and the only change I have made is to change the front turn signals for smaller ones.
I wonder if anyone else has notices that same thing, and whether there is a peak for this.
