Overview
The 2017 Kawasaki Z900 requires valve clearance check every 16,000 miles or 2 years. Regular valve clearance maintenance extends engine life and maintains peak performance. This guide covers the complete procedure for both DIY mechanics and those seeking shop estimates.
Important: Valve clearance must be checked on a cold engine. Incorrect valve clearance can cause engine damage or reduced performance.
Tools needed
Feeler gauges
Cam cover gasket set
Torque wrench
Shims (various sizes)
Socket set
Valve adjustment tool
Supplies needed
Cam cover gasket
Valve shims (if adjustment needed)
Engine oil
Thread locker
Step-by-step procedure
-
1Ensure the engine is completely cold (at least 3 hours after last run).
-
2Remove the fuel tank, side panels, and any obstructions to access the cam cover.
-
3Remove the cam cover carefully and set aside the gasket.
-
4Rotate the engine to Top Dead Center (TDC) on the compression stroke using the crankshaft bolt.
-
5Use feeler gauges to measure clearance between cam lobe and valve follower for all valves.
-
6Compare measured clearances to manufacturer spec (typically 0.08-0.18mm intake, 0.15-0.25mm exhaust).
-
7If clearance is out of spec, remove camshaft(s) and replace shims to achieve correct clearance.
-
8Reinstall camshaft(s) ensuring correct timing alignment.
-
9Install new cam cover gasket and torque cover bolts to spec.
-
10Reinstall fuel tank and panels. Start engine and listen for any ticking or unusual noise.
