I can only think that maybe you're turning the wrong nut. From memory think they make about ten turns. I read somewhere that the ideal weight for S1000R was 85 kg. I ended up with mind wound right out bar half a turn. I 'fit' the K1300R better, its bit more of a bruiser. I was far more confident throwing the GSA about than the S1000R. Yet to have a summer ride on the K so I'm undecided about that.
No correct adjuster, it's the big black one similar on the top of right front fork and on the rear shock think they are 15mm heads.
