2-30 PERIODIC MAINTENANCE
Drive Train Wear Inspection
Remove:
Chain Cover (see Swingarm Removal in the
Suspension chapter)
Rotate the rear wheel to inspect the drive chain
for damaged 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 Ib) 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, re-
place the claim. Also, replace the front and rear
sprockets when the drive chain is replaced.
Drive Chain 20-link Length
Standard: 317.5~318.2 mm (12.50~12.53 in.)
Service Limit: 323 mm (12.7 in.)
If the drive train wear exceeds the service
limit,replace the chain or an unsafe riding
condition may result. A chain that breaks or
jumps off the sprockets could snap 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. It is an endless type
and should not be cut for installation.

Swingarm (see Swingarm Removal in the
Suspension chapter)

of abnormal wear or damage.
