Racing cylinder of the Airsal 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 is included in the scope of delivery.

Plugs with a long thread must be used.

Technical data cylinder:

  • Ø inside intake manifold: 14 mm
  • Connection diameter intake manifold: 20 mm
  • Ø inside exhaust flange: 20 mm
  • Ø connection exhaust flange: 26 mm
  • Ø cylinder neck: 50.0 mm
  • Stroke: 44 mm
  • Bore: 43.5 mm
  • Thread for decompressor: M10 x 1.5 mm

Attention: For the Swiss 504 engines (42 mm stroke), the following modifications must be made to the cylinder:

  • Adjust 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.
  • For models with an external clutch lever, the intake must be extended, otherwise the carburettor may touch the clutch lever.

Further parts such as the required spark plug with long thread can be found in the accessories.

Quality product from the Spanish manufacturer Airsal.
