Do not overfill the oil tank. The oil tank has a built-in pressure relief valve. If the oil tank is overfilled, excessive pressure is created in the oil tank. The pressure relief valve will open to relieve the pressure and prevent damage to the oil tank. Excessive oil due to overfilling will also be forced out the pressure relief valve when it opens.
NOTICE
Do not overfill oil. Doing so can result in oil carryover to the air cleaner leading to equipment damage and/or equipment malfunction. (00190b)
See Figure 3. Remove the filler cap and check the hot oil level on the dipstick.
Below the lower mark: Add only enough oil until the level reads between the upper and lower marks.
Between the upper and lower marks: It is safe to operate the motorcycle.
At (or above) the upper mark: Drain the oil until the level reads between the upper and lower marks.
Install the filler cap.
If oil was added, remove the filler cap and verify the engine oil level in the oil tank. Do not fill oil tank to a level above upper mark on the dipstick. Install the filler cap.
