2022 Kawasaki KX450X Engine Oil
Engine Oil
- In order for the engine, transmission, and clutch to function properly, maintain the engine oil at the proper level, and change the oil and oil filter periodically.
- Not only do dirt and metal particles collect in the oil, but the oil itself loses its lubricative quality if used too long.
WARNING
Motorcycle operation with insufficient deteriorated, or contaminated engine oil will cause accelerated wear and may result in engine or transmission seizure, accident, and injury. Check the oil level before each ride and change the oil according to the periodic maintenance chart in the Owner’s Manual.
Because of the semi-dry-sump lubrication system, the engine oil level indicated on the oil level inspection window will fluctuate depending on the motorcycle’s position and engine speed when the engine’s shut off. To ensure proper reading of the engine oil level, follow the Oil Level Inspection procedures closely.
NOTICE
Racing the engine before the oil reaches every part can cause engine seizure.
Oil Level Inspection
- If the oil has just been changed, let the motorcycle sit a few minutes allowing the oil to settle.
- Start the engine and run it for several minutes at idle speed. Do not run the engine at high engine speed.
- Stop the engine and wait several minutes for the oil to settle.
- Check the engine oil level with the motorcycle vertical through the oil level inspection window on the lower right side of the engine. The oil level should come up between the high and low-level lines next to the oil level inspection window.
NOTE
- If the oil level is too high, remove the excess oil using a syringe or other suitable device.
- If the oil level is too low, add the correct amount of oil through the oil filler opening. Use oil of the same type and brand as those the one that is already in the engine.
NOTE
If no oil appears in the oil level inspection window tip the motorcycle slightly to the right until oil is visible then return to an upright position. If no oil appears even when tipped at an extreme angle, remove the drain bolt to empty any oil that may be in the transmission and crankcase, reinstall the drain bolt and refill with the specified amount of oil.
