Kawasaki Ninja Service Manual / Crankshaft/Transmission / Pistons / Cylinder (Upper Crankcase) Wear Inspection

Split the crankcase (see Crankcase Splitting).
Remove the pistons (see Piston Removal).
Assemble the cylinder (upper crankcase) [A], the cylinder head [B] and the cylinder head gasket [C].
Tighten the cylinder head bolts (see Cylinder Head Installation in the Engine Top End chapter).
Put the crankcase upside down.

Cylinder (Upper Crankcase) Wear Inspection

Since there is a difference in cylinder wear (upper crankcase) in different directions, take a side-to-side and a front-to-back measurement at each of the two locations (total of four measurements) as shown in the figure.

If any of the cylinder inside diameter measurements exceeds the service limit, replace the crankcase.

10 mm (0.39 in.) [A] 60 mm (2.36 in.) [B]

Cylinder (Upper Crankcase) Inside Diameter

Standard: 75.994 76.006 mm
(2.9919 2.9924 in.)

Service Limit: 76.09 mm (2.996 in.)

Crankshaft Sensor Inspection
Disconnect the crankshaft sensor lead connector (see Crankshaft Sensor Removal). Set the hand tester [A] to the × 10 Ω range and connect it to the crankshaft sensor lead connector [B]. Special Tool - Hand Tester: 57001-1394 Crankshaft Sensor Resistance Connections: Meter (+ ...

Premuffler Chamber Installation
Replace the premuffler chamber gasket [A] with a new one. Install the premuffler chamber gasket to the premuffler chamber [B] until it is bottomed so that the chamfer side faces exhaust pipe [C]. Install the exhaust pipe clamp [D] as shown in the figure. Insert the projection [E] into ...
