Well, just got back from the Isle of Man. I had a good play with pre-load and compression damping and it did make quite a difference, so much so that the suspension felt perfect on the ride there, two-up fully loaded, but when I was riding round the island one-up after dumping all the luggage I had to put the compression damping down again as the front was too stiff and harsh. You're dead right about pre-load, Celtic, just moves the rest position.
