Periodic Maintenance Procedures
Drive Chain Wear Inspection
Remove the chain cover (see Drive Chain Removal in the
Final Drive chapter).
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: 319 mm (12.56 in.)
A chain that breaks or jumps off the sprockets
could snag on the engine sprocket or lock the
rear wheel, severely damaging the motorcycle and
causing it to go out of control. Inspect the chain for
damage and proper adjustment before each ride.
If chain wear exceeds the service limit, replace it
with the standard chain.
Chain Guide Wear Inspection
Remove the swingarm (see Swingarm Removal in the
Visually inspect the chain guide [A].
Replace the chain guide if it shows any signs of abnormal
wear or damage.
