A few hundredths of a millimeter can make all the difference.
This 2025 Kawasaki Ninja ZX-6R came in at 12,800 miles for a complete valve-clearance inspection and adjustment.
Every valve was individually measured and documented. All eight exhaust valves required correction, so the camshafts were removed, the necessary shim changes were calculated, and the clearances were brought back within factory specification. Cam timing was then verified before reassembly and final testing.
Tight valve clearances can affect compression, starting and long-term valve-train durability—especially on an engine designed to live at high RPM.
Measured. Documented. Corrected—not guessed.
