Ride Height on the expert X

[kingtut]

I took the 121" out and extended it with muffin work extensions to a 144 and put it back in but it seems to me that the back of the sled rides pretty high and puts more pressure on the skis causing an insane amount of darting to happen. Anyone know how to adjust the ride height? I remember I needed to take out the adjuster for the softness adjustment if that makes a difference. I am 170 pounds w/o gear and most likely 180-185 with gear.
