Cylinder distortion
Check the gasket surface of the cylinder for distortion.
Use a straightedge and thickness gauge. Take clearance readings at several places. If any reading exceeds the service limit, replace the crankcase set.
Special tool : 09900–20803 (thickness gauge)
Cylinder distortion service limit: 0.02 Mm (0.0008 In)

Cylinder bore
Measure the cylinder bore diameter at six places. If any one of the measurements exceed the limit, overhaul the cylinder and replace the piston with an oversize piston.
The remaining cylinders must also be rebored accordingly; otherwise, the imbalance might cause excessive vibration.
Special tool (a): 09900–20530 (cylinder gauge set)
Cylinder bore standard: 74.500 – 74.515 Mm (2.9331 – 2.9337 In)
