2-34 PERIODIC MAINTENANCE
Wheel Alignment Inspection
Check that the notch [A] on the left alignment indicator [B]
aligns with the same swingarm mark or position [C] that
the right alignment indicator notch aligns with.
If they do not, adjust the chain slack and align the wheel
alignment (see Drive Chain Slack Adjustment).
Wheel alignment can be also checked using the
straightedge or string method.
Misalignment of the wheel will result in abnormal
wear, and may result in an unsafe riding condition.
Drive Chain Wear Inspection
Chain Cover (see Swingarm Removal in the Suspension
Rotate the rear wheel to inspect the drive chain for dam-
aged rollers, and loose pins and links.
If there is any irregularity, replace the drive chain.
Lubricate the drive chain if it appears dry.
Stretch the chain taut by hanging a 98 N (10 kg, 20 lb)
weight [A] on the chain.
Measure the length of 20 links [B] on the straight part [C] of
the chain from the pin center of the 1st pin to the pin center
of the 21st pin. Since the chain may wear unevenly, take
measurements at several places.
If any measurements exceed the service limit, replace the
chain. Also, replace the front and rear sprockets when the
drive chain is replaced.
Drive Chain 20-link Length
317.5 ∼ 318.2 mm (12.50 ∼ 12.53 in.)
Service Limit: 323 mm (12.7 in.)
If the drive chain wear exceeds the service limit, re-
place the chain or an unsafe riding condition may
result. A chain that breaks or jumps off the sprock-
ets could snag on the engine sprocket or lock the
rear wheel, severely damaging the motorcycle and
causing it to go out of control.
For safety, use only the standard chain.
