Cylinder head with pre-installed decorative valve and a 43 mm diameter, compatible with your moped equipped with a Sachs 503 AAL / ABL / 2AL or 2BL CH engine.
The cylinder head cover is neatly finished and fits both original Sachs cylinders and aftermarket cylinders with a 43 mm diameter. The combustion chamber geometry has been modified from the original to improve combustion.
The decompression valve is already pre-installed. This allows for plug-and-play installation of the cylinder head.
The package includes four copper rings, which provide additional sealing due to the small sealing surface in the mounting area.
A high-quality, affordable standard replacement part. GPO – GOOD PARTS ONLY.
