GENERAL INFORMATION CHECKING LEVEL HYDRAULIC CLUTCH Remove the cover to check the oil level in the master cylinder of the clutch. Remove the screws (1) and lift off the cover together with the rubber boot (2). The oil level should be 4 mm below the upper edge when the master cylinder is in a horizontal position.
GENERAL INFORMATION CLEANING Clean the motorcycle regularly to retain the beauty of the plastic parts. Use warm water with a commercial detergent and a sponge. Coarse dirt can be removed with a soft water jet. CAUTION: never clean the motorcycle with a power washer or a high pressure jet. This will cause the water to reach the electric components, socket connectors, cables, bearings, carburetor, etc.
