I had a 1971 Bonnie, first of the oil in frame models (actually oif were produced in 1972, but mine was an experimental model) it didn't have a kill switch!
Mine was sold as a 1971 model and I believe that was the year that I bought it from a dealer in Daly City, CA, long since departed. I paid $1200 for the bike and I eventually counted 15 factory-installed defects, including the main jets just sitting in the float bowls, a defective oil pressure sensor and the frame oil drain plug needing a 250 foot-pound air gun to loosen it.
When I left the dealership, at the first left turn traffic light, when I stopped I put my foot down and fell over because the pavement was further away than I had expected.
