Notes:
Plugs with long thread must be used.
The following modifications must be made to the cylinder on Swiss 504 engines (42 mm stroke):
- Adjust the cylinder base and gasket as shown in Figure 6 .
- The cylinder base must be turned off so that the compression is adjusted again due to the shorter stroke, we recommend setting a crushing edge of 0.8 - 1.0 mm.
- On models with an external clutch lever, the intake must be extended, otherwise the carburetor may come into contact with the clutch lever.
Other parts such as the required spark plug with long thread can be found in the accessories section.
