Piston And Piston Ring - Suzuki LT-Z90 Manual

3-32 ENGINE
CYLINDER BORE
Inspect the cylinder wall for any scratches, nicks or other dam-
age. Measure the cylinder bore diameter at six places.
If any one of the measurements exceed the limit, replace the cyl-
inder.
Cylinder bore
Standard: 45.500 – 45.515 mm (1.7913 – 1.7919 in)
09900-20530: Cylinder gauge set
09900-20513: Rod (40 mm)

PISTON AND PISTON RING

PISTON DIAMETER
Measure the piston outside diameter at 10 mm (0.4 in) A from
the piston skirt end using a micrometer.
If the measurement is less than the limit, replace the piston.
Piston diameter:
Service Limit: 45.380 mm (1.7860 in)
at 10 mm (0.4 in) from the skirt end
09900-20204: Micrometer (25 – 50 mm)
PISTON-TO-CYLINDER CLEARANCE
Subtract the piston diameter from the cylinder bore diameter.
( above)
If the piston-to-cylinder clearance exceeds the service limit,
replace the cylinder or the piston, or both.
Piston-to-cylinder clearance:
Service Limit: 0.120 mm (0.0047 in)
