4. To clean the filter, tap it on a hard surface to dislodge any dirt and use compressed air to clear the element, directing the air in the opposite way to normal flow (see illustration). Do not use any solvents or cleaning agents on the element as it is pretreated with a dust adhesive. If the machine is constantly used in dirty or dusty conditions the filter should be replaced at more frequent intervals than specified. Check the element for tears and excessive oil contamination and replace it with a new one if necessary.

5. Install the filter In the housing, making sure it is correctly seated, and secure it with its screws or cover. Install the side panel or fuel tank as required according to model.
Sub air-filter
Note: There is no specific interval for cleaning the sub-air filter, but it should be inspected periodically to ensure the carburettor air vent system is clear.
6. XL600V models have two sub-air filters, one on the back of each radiator - remove the fairing side panels to access them (see Chapter 8). XL650V models have one sub-air filter, mounted on the rear of the air filter housing.
7. On XL600V-T to X (1997 to 1999) models and XL650V models, remove the cover on the sub-air filter element housing(s), then remove the element and check for damage and excessive dirt or oil contamination and replace with new one(s) if necessary (see illustrations).
