I have an 08 CRF 450 with 160 hrs, ride mx only. I have approximately 2-3mm movement and an audible clunk when I grab the lower fork legs and push back and forth while the bike is on the stand. I rebuilt the legs 20hrs ago including all 3 bushings (including sliders) and new seals. It is not the steering stem bearings, because when I attempt to move the upper legs there is no movement. Never noticed this before, and was wondering if this was normal. Thanks for your input.
