The preload adjuster on my 2010 40 Rc2 keeps keeps self adjusting while riding. One run equals 2 or 3 turns of the adjuster. The adjuster is not loose. It seems to have just the right resistance when turning it, yet it keeps turning on its own. I don't run much preload anyways.........anout 7 or 8 clicks,but its a bit of a pain on a brand new fork.
