Please select the desired cylinder head with or without decompression bore and the desired exhaust clamp in the selection field.
Note: The original stud bolts of the engine housing are too short due to the height of the cylinder kit and must be replaced with longer bolts (item 24319).
For Zündapp engines with an 85 mm short connecting rod, this must first be converted to a long connecting rod with a length of 91 mm (center - center) in order to use the cylinder.
