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.

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.)
