10 – 20 mm (0.4 – 0.8 in)
Do not use trichloroethylene, gasoline or any similar
solvent. These fluids will damage the O-rings. Use
only kerosine to clean the drive chain.
* 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.
