Synthetic two stroke oils have eliminated "fouled-plug syndrome" and well restored and maintained Bantams will reliably (but slowly) cover reasonably long distances on ride days.
The four bike below are pictured in the town of Willunga in South Australia.
The bikes are: 1954 D1 plunger, 1949 D1 rigid, 1956 D3 pivoting frame and 1960 D7 swing-arm.
While you don't need to stop to fix the fouled plugs you'll note that coffee and cake is a standard requirement! "
