• 15-link section "a" of the drive chain
Out of specification → Replace the drive
chain.
15-link length limit
239.3 mm (9.42 in)
a. Measure the length "b" between the inner
sides of the pins and the length "c" be-
tween the outer sides of the pins on a 15-
link section of the drive chain as shown in
the illustration.
b. Calculate the length "a" of the 15-link sec-
tion of the drive chain using the following
formula.
Drive chain 15-link section length "a" =
(length "b" between pin inner sides +
length "c" between pin outer sides)/2
TIP
• When measuring a 15-link section of the drive
chain, make sure that the drive chain is taut.
• Perform this procedure 2–3 times, at a different
location each time.

NOTICE
• This motorcycle has a drive chain with
small rubber O-rings "1" between the drive
chain side plates. Never use high-pressure
water or air, steam, gasoline, certain sol-
vents (e.g., benzine), or a coarse brush to
clean the drive chain. High-pressure meth-
ods could force dirt or water into the drive
chain's internals, and solvents will deterio-
rate the O-rings. A coarse brush can also
damage the O-rings. Therefore, use only
kerosene to clean the drive chain.
