Cylinder base gasket in 0.8mm thick version (so-called spacer).
This allows the control angle of the cylinder to be increased / adjusted and / or the compression / squish edge to be regulated. Ideal for engines that are operated with more stroke than series.
Fits almost all cylinders for PX80, PX125, PX150
The overcurrent cutouts are in std size.
These can of course also be adapted (manually milled) for cylinders with larger cutouts.
