I have a 2006 F4 1000S. I have been working to adjust the front spring preload. How hard should it be to change the preload settings? I am sure I am trying to turn the adjuster nut in the right direction. No matter how hard I try to turn the nut it won't budge. I hope somebody has some information to share on this problem.
Thanks for your time,

At the risk of stating the obvious, are you sure you are turning the correct nut? The outer one is the fork cap and the inner one is the preload. Clockwise adds preload, anti-clockwise removes preload. It should turn relatively easily until it bottoms out and the it won't turn any more. It should be pretty easy to go the opposite direction to see if you are at the end of mechanical adjustment.

Ouch, I had thoughts along those lines too Rob, just did not have the guts to ask. What happened to me however might be useful too.
I assembled my forks wrongly, by winding the the preload adjuster fully in and then fitting the fork cap to the fork tube and damping rod. What then happened, as I turned my preload anti-clock wise to remove some preload, I actually unwound the damping rod and the bottom of my forks dropped out, lucky those brake lines are strong.:jsm:
Re-read the manual only to find they do stress that the preload adjuster should be wound out fully before assembly starts. Another lessen picked up in the field.:)

The blunt approach has its uses and most of my lessons were learned the hard way as well. I've stripped a fork cap or two in my day...
