Periodically check that the nut-and-spindle assembly and the needle roller bearings of the swinging arm are properly tightened.
Inspection procedure:
Place the motorcycle on the front service stand (OPT); see 1.7.1.
Remove the fuel tank; see 4.1.1.
Fix the slings to the frame at the engine top mounting point.
Lift hoist arm until stretching the slings taut.
Push and pull the rear wheel up and down, then rock it from side to side. If you feel any play, adjust the swinging arm; see 2.17.3.
If this fails to eliminate play, change the bearings; see 7.11.2.
