I've got a 2001 640 Adv and never have been able to figure out which way to turn the rear rebound damping adjustment. The KTM owners manual says "turn the knob to the left side to increase damping" but that would depend on whether you're looking forward or backward? The WP manual says "turn the switch clockwise to increase damping". Once again it would depend on your point of view? What really confuses me is, if I take the most obvious sense of both sets of directions they give the opposite answer. Can anybody help me???
