First 41 - 43 mm cylinder head in original look with enlarged fins, suitable for Sachs 502, 50/2, 50/3, 50/4 engines.
Thanks to the larger fin design, the cylinder head can optimally dissipate heat even at high temperatures and slow uphill rides.
The hole for the decompressor is prepared and threaded (M10 x 1.5 mm). If a decompressor is installed, it only needs to be drilled through with a 3 mm drill bit.
Ø Cylinder: 41.0 - 43.0 mm (type L)
Perforation pattern for cylinder head screws: 37 x 37 mm
Decompressor thread: M10 x 1.5 mm
Ø Silentblower mount: 19.3 mm
Ø outside: 108 mm
Ø outside under casing: 86 mm
The cylinder head is installed without gasket, the tightening torque of the cylinder head bolts (strength 10.9) is 11 - 13 Nm.
Matching add-on parts such as spark plugs, decompressors, silentblowers etc. can be found in the accessories section.
