Cylinder Base Gasket
NOTE:
The general procedure is to install a new
gasket of the same thickness. However, if you do
not know the gasket thickness that was installed
or if a crank repair has involved replacement of
connecting rods, refer to the COMBUSTION CHAM-
BER VOLUME MEASUREMENT to properly deter-
mine the required gasket thickness.
Different thicknesses of cylinder base gaskets are
used for a precise adjustment of the combustion
chamber volume.
To identify gasket thickness, refer to the identifi-
cation holes on the gasket.
