F800GS rear suspension adjustment. OK, I can adjust the preload damping of the rear suspension with the knob, but I have ESA which means that the rebound screw is missing from the bottom of the rear shock. Do I use ESA to adjust the rebound e.g. two up with luggage with out ESA rebound is 1 turn of the screw which stiffens up the rebound, so would setting ESA to sport have the same effect or should I just leave it on Normal?
