70cc Cylinder Head for Minarelli AM. This aluminum cylinder head features a large combustion chamber, suitable for the Minarelli AM 70cc cylinder set from NARAKU (Part Number: NK102.68 / NK103.93) and for other 70cc cylinders with a 47mm diameter. The larger combustion chamber addresses issues with electric start due to the higher compression of the cylinder sets. It is Euro 1 type, but is also suitable for Euro 2-4 models. It is recommended to use only cylinder flange kits compatible with Euro 1 models.
