NOTES: The squish gap can be set to a different thickness with
cylinder foot seals. Cylinder foot seals are available
0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm and 0.8 mm thick.
Example Engine model: 125 MAX
A cylinder base gasket 0.5 mm thick has been installed. With this cylinder
base gasket a squish gap of 0.8 mm was measured. A cylinder base gas-
ket 0.8 mm thick is required to set the required value, e.g. 1.1 mm. Of
course a 0.5 mm and a 0.3 mm seal can be installed.
If it is necessary to install a cylinder base gasket with a
different thickness, the cylinder can be completely re-
moved by unscrewing the four studs. Follow the directions
in the “Installation of the cylinder” chapter for installation
of the cylinder.
