Engine Oil/Filter Change

Follow all instructions carefully. Do not overfill.
Change the engine oil at the intervals specified in the periodic maintenance table beginning on Periodic Maintenance Table. Change the oil more frequently if the motorcycle is subjected to severe use, especially operation in cold weather. See Severe Use Definition. Always use the recommended oil. See Engine Oil Recommendation.
NOTICE
Failure to perform frequent oil changes during cold weather operation can result in condensation forming. Freezing condensation can result in plugged oil lines and serious engine damage.
NOTICE
After an oil change, the low oil pressure indicator may illuminate when the engine is started. If this occurs, do not increase RPM above idle speed until the indicator turns off. Operating above idle speed could result in damage to the engine.
  1. Change the oil and filter when the engine is warm. If the engine is cold, start the engine and allow it to run at idle for at least five (5) minutes.
  2. Park the motorcycle with the sidestand down on a firm, level surface. For proper oil drain, use a service lift to ensure the motorcycle is vertically centered.
  3. Clean the area around the two drain plugs . Place a drain pan under both drain plugs.

    caution
    Hot oil can cause burns to skin. Do not allow hot oil to contact skin.
  4. Remove the drain plugs. Allow the oil to drain completely.

  6. Reinstall the drain plugs.

  7. Place a drain pan or shop towels under the oil filter. Using an oil filter wrench, turn the filter counter-clockwise to remove it. If necessary, remove the horn bracket to improve access.
  8. Using a clean dry cloth, clean the filter sealing surface on the engine.
  9. Lubricate the o-ring on the new filter with a film of fresh engine oil. Check to make sure the o-ring is in good condition.
  10. Install the new filter and rotate it clockwise by hand until the filter gasket contacts the sealing surface, then turn it an additional 3/4 to one full turn.
  11. Reinstall the horn bracket if it was removed.
  12. Remove the dipstick. Using a funnel, add 3-4 qt (2.8-3.8 L) of the recommended oil. Reinstall the dipstick securely.
  13. With the motorcycle in an upright, centered position, start the engine and allow it to idle for 30 seconds. Stop the engine.
  14. Add the recommended oil as needed to bring the level to the FULL mark on the dipstick. Verify the level on the dipstick.
    NOTICE
    The approximate volume between the ADD and FULL marks on the dipstick is 16 fl oz (.45 L).
  15. Reinstall the dipstick securely
    NOTICE
    Do not overfill. Overfilling can result in loss of engine performance and an oil-saturated air filter. Use a suction device to remove excess oil if overfilled.
  16. Dispose of used filter and oil properly.
    NOTICE
    After an oil change, the low oil pressure indicator may illuminate when the engine is started. If this occurs, do not increase RPM above idle speed until the indicator turns off. Operating above idle speed could result in damage to the engine.
