Kawasaki Ninja Service Manual: Valve-to-Guide Clearance Measurement (Wobble Method)

Kawasaki Ninja Service Manual / Engine Top End / Valves / Valve-to-Guide Clearance Measurement (Wobble Method)

If a small bore gauge is not available, inspect the valve guide wear by measuring the valve to valve guide clearance with the wobble method as indicated below.

Insert a new valve [A] into the guide [B] and set a dial gauge against the stem perpendicular to it as close as possible to the cylinder head mating surface.
Move the stem back and forth [C] to measure valve/valve guide clearance.
Repeat the measurement in a direction at a right angle to the first.

If the reading exceeds the service limit, replace the guide.

Valve-to-Guide Clearance Measurement (Wobble Method)

NOTE

The reading is not actual valve/valve guide clearance because the measuring point is above the guide.

Valve/Valve Guide Clearance (Wobble Method) Standard:

Exhaust 0.03 0.12 mm (0.0012
0.0047 in.)

Intake 0.03 0.13 mm (0.0012
0.0051 in.)

Service Limit:

Exhaust 0.34 mm (0.013 in.)

Intake 0.36 mm (0.014 in.)
