My 03 CRF 450 forks are jacked! They sag about an inch on the top, feel spongy, and when they extend between bumps they smack and feel like they want to pull out of the clamps. I can hear the smack and feel it in my hands big time. I had the springs changed to suit my weight and changed the oil height about a year ago but have only gotten to ride 5 times this year. Any ideas?
