To check the condition of the steering column bearings, place the motorcycle on the center stand and hang the front wheel (the wheel must not touch the ground).
1. Holding the steering wheel, slowly turn the fork left and right from lock to lock. The fork should move smoothly, without jamming, clicking or extraneous sounds. If there is even a slight change in fork torque, the bearings must be replaced (see «Steering column - disassembly, assembly, replacement of bearings»). Also, bearings must be replaced if steering wheel sticking is felt in «zero» (direct) position.
2. Grasping the ends of the fork legs in their lower part, we try to rock the fork back and forth. The slightest play in the steering column is a reason to check and adjust the tightness of the bearings or replace them.
3. We are trying to shake the fork in the up and down direction, parallel to the axis of the steering column. Any play in this direction in the steering column indicates insufficient tightening of the steering column bearings or their failure. If play is felt in the junction of the movable and bearing tubes of the fork feathers, the guide forks require replacement (see «Feathers of a forward fork - check and replacement of epiploons (disassembly and assembly)»).
