Air filter

CAUTION

Perform

maintenance operations more frequently
than the indicated intervals if you are riding
in rainy or dusty conditions, on rough road
surfaces or when the vehicle is used for
racing.

CAUTION

Partial cleaning of the air filter does not

eliminate the need to change the filter at

the specified intervals. Do not start the

engine when the air filter is not in place.

Do not clean the filter element with

petrol or solvents. These products may

cause the fuel to ignite in the fuel

system, leading to personal injury and

vehicle damage.
