Install the new oil filter cartridge, and then tighten it to the specified torque with a torque wrench. Install the engine oil drain bolt, and then tighten it to the specified torque. Tightening torque: Engine oil drain bolt: 43 Nm (4. 3 m·kg) @ EC000067 CAUTION: q In order to prevent clutch slippage (since the engine oil also lubricates the clutch), do not mix any chemical additives with the oil or use oils of a higher grade than "CD".

Do not use hard water or salt water since it is harmful to the engine. q If water has been used instead of coolant, replace it with coolant as soon as possible, otherwise the engine may not be sufficiently cooled and the cooling system will not be protected against frost and corrosion. q If water has been added to the coolant, have a Yamaha dealer check the antifreeze content of the coolant as soon as possible, otherwise the effectiveness of the coolant will be reduced. 14. If necessary, add sufficient coolant until it reaches the top of the radiator, and then install the radiator cap. If necessary, remove the coolant reservoir cap, add coolant to the maximum level mark, and then install the cap.

Check and, if necessary, correct the tire air pressure, and then lift the motorcycle so that both of its wheels are off the ground. Alternatively, turn the wheels a little every month in order to prevent the tires from becoming degraded in one spot. Cover the muffler outlet with a plastic bag to prevent moisture from entering it. 9. [. . . ]
