@Sabine: yeah i know i am a little guinea pig ..... But now come the two advantages out of this.
a) i can rip that bike to pieces to satisfy my old mechanic desires (and i stand last evening in the garage to de-assemble here a bit and there a bit and put it together again. ... love to do that and see a lot of things could be improved)

b) my wife asked my to buy a F800GS to have at least one good bike .... yeeeeeeeehh .... THANK YOU, SHINERAY !!!!!!
