This is my 10th ride on a 09 162 M8 SP and over the past 2 rides I have had virtually no suspension travel. I have tried tightening my track and running between 210-230 PSI in the rear shock but once I go about 5 min in the bumps my rear bumper is down and my flap is dragging on the ground. I had a great 15 mile ride down from the alpine over a nasty trail. Any advice would help my back
