Periodic Maintenance Procedures
Steering
Steering Inspection
•
Turn the handlebar left and right, and check the steering
action.
If the steering action is not smooth, or if the steering binds
or catches before the stop, lubricate the steering stem
bearing.
NOTE
○
The cables and wires will have some effect on the steer-
ing action which must be taken into account.
•
Check the steering action again.
If steering stem bearing lubrication does not remedy the
problem, inspect the steering stem for straightness, steer-
ing stem clamps, and tie-rod bearings.
If you feel looseness, or if the steering rattles as it turns,
check the tightness of the steering bolts and nuts.
•
Tighten loose bolts and nuts to the specified torque (see
Steering chapter), and check the steering action again.
If the steering action does not change by tightening the
bolts and nuts, inspect the steering stem clamps, steer-
ing stem bearings, tie-rod bearings, and steering knuckle
joints.
Electrical System
Spark Plug Cleaning/Inspection
•
Remove the spark plug (see Electrical System chapter).
•
Clean the spark plug, preferably in a sandblasting device,
and then clean off any abrasive particles. The plug may
also be cleaned using a w ire brush or other suitable tool.
If the spark plug electrodes are corroded or damaged,
or if the insulator is cracked, replace the plug. Use the
standard spark plug or its equivalent.
Spark Plug Gap Inspection
•
Measure the gap [A] with a wire-type thickness gauge.
If the gap is incorrect, carefully bend the side electrode
[B] with a suitable tool to obtain the correct gap.
Spark Plug Gap
0.7 ∼ 0.8 mm (0.028 ∼ 0.032 in.)
