Exactly! We have an '07, same issue. I purchased the bike new in '07 & saved it until the 2010 race season when I finally set the bike up, much like my '03 & '04's are. Like my favorite "M" models, I swapped my internally 1" lowered suspension on to the '07, ran 15mm above the upper clamps on the fork tubes and the standard 3.75" sag out back. I never noticed the handling issue as much in the rocks, but in Southern NJ, especially in what we call "waltzing tight" (tree littered trail just open enough & enough rhythm to clip through in 3rd gear or so), no matter how I adjusted the suspension settings, I'd get this knife & wash sensation that eventually caused me some wicked higher speed crashes and lost confidence over time. I ran the bike the whole season but I didn't figure this out until the end of the season. I had no time while racing to really address it, so I forsaken it & handed it off to my husband to deal with in place for my favorite old '04 (which I'm still racing now off-road).
Now he found a few bandaids to help alleviate the steep steering head angle short of welding which is the best way (which is the next thing we're doing to it) & has gotten it to work pretty well for himself, even coming to terms with it, though I'm still gun shy of it (concussions will do that to a person). He dropped the forks a few millimeters in the clamps until he found a happy middle ground and dialed in a hair more sag then we usually run. That dang bike has the steering handle angle of a trials bike, lol!
