I am having a bit of a problem with my '01's rear suspension bottoming out landing even a small jump. I've set the spring height and stiffened the dampening and am now wondering if I need a new spring. What are the weight ranges for the different springs for riding semi-aggressively. I am not small @ 6'5" and 235lbs. and have never tuned the suspension on a dirt bike before, in fact the '01 is my first ever so I am learning as I go. Any help would be appreciated.
