I followed the service manual steps on tightening the steering head nut (the one below the top triple clamp). This gives me a smooth rotation from lock-to-lock for the bottom triple clamp. But once I place the top triple clamp on and tighten the top nut to the correct torque, the smooth rotation is gone. I made sure the nut below the top triple clamp is not turning as I torque the top nut down. What might I be doing wrong or are the bearings shot?
