Racing cylinder of the Athena brand for Sachs 504 (with adaptations), 505 & 508 engines, which were installed on Hercules mopeds / mopeds, among others.
Thanks to the large intake, overflow and exhaust, this tuning cylinder provides a significant increase in performance.
The intake manifold and exhaust flange are included in the scope of delivery.
Plugs with a long thread must be used.
Technical data cylinder:
- Ø inside intake manifold: 15 mm
- Connection diameter intake manifold: 20 mm
- Ø inside exhaust flange: 20 mm
- Ø connection exhaust flange: 25.7 mm
- Distance stud bolt exhaust flange: 50 mm
- Ø thread exhaust flange: M8
- Ø cylinder neck: 51.6 mm
- stroke: 44 mm
- bore: 45.0 mm
- Thread for decompressor: M10 x 1.5 mm
Attention: For Swiss 504 engines (42 mm stroke), the following modifications must be made to the cylinder:
- Adjust cylinder base and gasket as shown in Figure 5.
- 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.
- In the model with an external clutch lever, the intake must be extended, otherwise the carburettor may come into contact with the clutch lever.
Quality product from the Italian manufacturer Athena.
