Setting the sag is part of the job. You need to check the static sag to confirm the proper spring rate. Bleed the air out of the forks with the wheel off the ground. An 01, has the suspension ever been serviced? Everything wears out, except the springs. I have never heard of a spring wearing out on a dirtbike. You measure the free length of the spring to confirm that. But all the rest of the parts do! Put all the adjusters to the stock settings, and adjust to your liking. There is no suspension adjustment for hard landings, well, except learning to land smoother. Properly set, it should bottom on the roughest part of the track.
