Maintenance FAQs
- What is the recommended engine oil for the Z900?
- 10W-40 motorcycle oil meeting API SG and JASO MA standards. Kawasaki recommends their own brand. Change oil and filter every 3,800 miles.
- How often should I lubricate the chain?
- Lubricate the chain with a quality chain lube every 600 miles. Inspect for wear and adjust tension at the same time.
- What are the correct tire pressures?
- 36 psi front, 42 psi rear when cold. Check pressures before every ride.
- When should I replace the spark plugs?
- Replace the spark plugs (NGK CR9EIA-9) every 7,600 miles.
- How can I make my brakes last longer?

- Is valve adjustment difficult on the Z900?
- Checking/adjusting valve clearances requires removing the camshafts and is best left to experienced mechanics. Have valves inspected every 7,600 miles.
- My bike feels down on power. What could cause that?
