[QUOTE="Nige"] At the risk of sounding thick, something isn't right there on the front forks. I have cable tie on the bike now, just sitting on it at factory settings move it down 30mm or so. If i go out & hammer the bike to move it further down the leg how do i know whats 10mm below that point? I am not sure exactly what i'm trying to do if you know what i mean?[/QUOTE] The 10mm is how much travel isn't used. So the distance between the cable tie & the bottom of the forkleg (the 'bumpstop'). You don't need to know how much travel /is/ used, or how far the cable tie moves.
