Checking the drive chain

1. Measure:

• 15-link section "a" of the drive chain Out of specification Replace the drive chain.

a. Measure the length "a" between the inner sides of the pins and the length "b" between the outer sides of the pins on a 15-link section of the drive chain as shown in the illustration.

b. Calculate the length "c" of the 15-link section of the drive chain using the following formula.

Drive chain 15-link section length "c" = (length "a" between pin inner sides + length "b" between pin outer sides)/2

NOTE:

• 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.

2. Clean:

• Drive chain

a. Wipe the drive chain with a clean cloth.

b. Put the drive chain in kerosene and remove any remaining dirt.

c. Remove the drive chain from the kerosene and completely dry it.

CAUTION:

• 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 solvents (e.g., benzine), or a coarse brush to clean the drive chain. High-pressure methods could force dirt or water into the drive chain's internals, and solvents will deteriorate the O-rings. A coarse brush can also damage the O-rings. Therefore, use only kerosene to clean the drive chain.
• Do not soak the drive chain in kerosene for more than ten minutes, otherwise the Orings can be damaged.

3. Check:

• O-rings "1" Damage Replace the drive
  chain.
• Drive chain rollers "2" Damage/wear Replace the
  drive chain.
• Drive chain side plates "3" Damage/wear Replace the drive
  chain.

Cracks Replace the drive
chain.

4. Lubricate:

• Drive chain
