Terry your right about the static sag, but you need to take the initial measurement with the rear suspension having no load on it, easy if you've got a centre stand or abba stand. Then measure again with the normal rider sat on the machine in the normal riding position. Try and get this as close as poss to 30mm by increasing or decreasing the pre load setting. The same can be done with the front pre load on the forks, but with the measurement being 20mm. But remember both unload measurements need to be taken with the suspension having no load on it.
I've got a detailed set up somewhere in my tool box, I'll try and post it for reference purpases.
Hope this helps
, oh and try setting any damping settings back to the original factory settings. I'm sure these can be found online.
