CLEANING AND LUBRICATING
• Clean the drive chain with kerosine. If the drive chain tends to
rust quickly, the intervals must be shortened.

Do not use trichloroethylene, gasoline or any similar
solvent. These fluids will damage the O-rings. Use
only kerosine to clean the drive chain.
• After cleaning and drying the chain, oil it with a heavy-weight
engine oil.

* Do not use any oil sold commercially as "drive chain
oil". Such oil can damage the O-rings.
* The standard drive chain is DID520V. Suzuki recom-
mends to use this standard drive chain as a replace-
ment.
