Steering Play Inspection
- Raise the front wheel off the ground with the jack (see Front Wheel
Removal in the Wheels/Tires chapter).
Special Tool - Jack: 57001-1238
- With the front wheel pointing straight ahead, alternately tap each end
of the handlebar. The front wheel should swing fully left and right from the
force of gravity until the fork hits the stop.
If the wheel binds or catches before the stop, the steering is too tight.
- Feel for steering looseness by pushing and pulling [A] the forks.
If you feel looseness, the steering is too loose.
- The cables and wiring will have some effect on the motion of the fork which must be taken into account.
- Be sure the leads and cables are properly routed.
- The bearings must be in good condition and properly lubricated in order for any test to be valid.

WARNING If the handlebar does not turn to the steering stop it may cause an accident resulting in injury or death.
Be sure the cables, harnesses and hoses are routed properly and do not interfere with handlebar movement (see Cable, Wire, and Hose Routing section in the Appendix chapter).

- Visually check the outer races and the ball bearings.
Replace the bearing assemblies if they show wear or damage.
- Pack the upper and lower ball bearings in the cages with grease, and apply a light coat of grease to the upper and lower outer races.
