Thats what I came to say. Adjust your preload(and get it rebuilt). Adjust your front shocks preload too so the belly of the quad stays parallel to the ground, the front of the quad should actually be a up to a 1/4 inch higher than the rear. Measure ride height below or just in front of the footpegs and 19 or 20 inches in front of the footpegs. Measure from the bottom of the frame rail to the ground. Try to keep your front end up higher than the rear end. Adjust the rear shock preload by tightening the big adjuster ring at the top of the shock. Adjust the front shocks preload by spinning the shock body up to a higher notch found on the lower 1-4 of the shock, just below the spring. Measure your ride height with you, in all your riding gear, standing on the footpegs, have a buddy make the measurements. Good luck.
