Disassembly
note

Use fender covers to avoid damaging painted surfaces.

To avoid damaging the cylinder head, wait until the engine coolant temperature drops below normal temperature (20°C [68°F]) before removing it.

Piston Rings
1.

Inspect the piston ring side clearance.

Using a feeler gauge, measure the clearance between new piston ring and the wall of ring groove.

Piston ring side clearance

No.2 : 0.070 ~ 0.110 mm (0.0028 ~ 0.0043 in)

Oil ring : 0.030 ~ 0.070 mm (0.0012 ~ 0.0028 in)

If the clearance is greater than maximum, replace the piston.

2.

Inspect the piston ring end gap.

To measure the piston ring end gap, insert a piston ring into the cylinder bore. Position the ring at right angles to the cylinder wall by gently pressing it down with a piston. Measure the gap with a feeler gauge.

Piston ring end gap

No.1 : 0.18 ~ 0.33 mm (0.0071 ~ 0.0130 in)
