This model was made summer 2013.
I dismantled after very much effort and with even more patience and courage the head that was untouched and didn’t run for over 45 years.
The actual form of the camfollowers differed from the patentdrawings. There was not enough room within the 175 cc Ducati head to use rollers.
Cenna used standard Ducati rockers and welded a second arm with hollow (concave) closing cam followers.
