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

Split the crankcase (see Crankcase Splitting).
Remove the pistons (see Piston Removal).

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.)
