Kawasaki Ninja Service Manual / Periodic Maintenance / Periodic Maintenance Procedures / Engine Top End / Valve Clearance Inspection

NOTE

Valve clearance must be checked and adjusted when the engine is cold (at room temperature).

Remove: Crankshaft Sensor Cover (see Crankshaft Sensor Removal in the Electrical System chapter) Cylinder Head Cover (see Cylinder Head Cover Removal in the Engine Top End chapter)
Turn the crankshaft, align the #1, 4 mark on the timing rotor with the crankcase timing mark.

Valve Clearance Inspection

Using a thickness gauge [A], measure the valve clearance between the cam and the valve lifter.

Valve Clearance

Standard: Exhaust 0.17 0.22 mm (0.0067
0.0087 in.)

Intake 0.15 0.22 mm (0.0059
0.0087 in.)

Valve Clearance Inspection

NOTE

Thickness gauge is horizontally inserted on the valve lifter.

Valve Clearance Inspection

When positioning #1 piston TDC at the end of the compression stroke:

Intake Valve Clearance of #1 and #3 Cylinders Exhaust Valve Clearance of #1 and #2 Cylinders Measuring Valve [A]

Valve Clearance Inspection

When positioning #4 piston TDC at the end of the compression stroke:

Intake Valve Clearance of #2 and #4 Cylinders Exhaust Valve Clearance of #3 and #4 Cylinders Measuring Valve [A]

Valve Clearance Inspection

If the valve clearance is not within the specified range, first record the clearance, and then adjust it.

Valve Clearance Adjustment

To change the valve clearance, remove the camshafts (see Camshaft Removal in the Engine Top End chapter) and valve lifters. Replace the shim with one of a different thickness. NOTE Ma ...
