2. Measure the cylinder bore with a cylinder gauge at the three levels indicated, in the directions A and B.

Level 2: Center of cylinder

3. If the cylinder bores show more than the specified out-of-round or taper, or if the cylidner walls are badly

scuffed or scored, the cylinder block should be rebored and honed. New oversize pistons and rings should be

Standard value

Cylinder bore : 86.7 mm (3.41 in.)

Out-of-round and taper of cylinder bore :

5. Oversize pistons are available in two sizes.

Piston service size and mark mm (in.)

0.25 (0.010) O.S : 0.25

6. To rebore the cylinder bore to the oversize, maintain the specified clearance between the oversize piston and

the bore and make sure that all used pistons are the same oversize. The standard measurement of the piston

outside diameter is taken at a level of 15.5mm (0.61in.) above the bottom ofthe piston skirt and across the
