🤣 busted. The clam shells and front cover were me giving them a clean and running steel wool over them, although on all of the air heads I’ve owned, these items have a much smoother finish than the engine and gearbox casings and tend to have a slightly different colour. The bike was bought in 1975 w...

As I have said before, the bike has a nice history and the previous owner from 1975 to 1985 has provided a number of written accounts of long trips on the bike with his wife on pillion (I guess the seat cannot be that uncomfortable on long journey...

Fortunately the filter hadn't collapsed. Are the German-made filters still marked 'West Germany' or have they unifie...
