I have seen bikes that have started out as foot shift or clutch converted to both clutch and shifting done by hand. They used either a modified tank shift or long jockey shift with a hand clutch attached to the shifter.
Then, there was the trick my uncle used. He really wanted to go to a dance over in the next town, but decided the road was too icy to drive his car. So, he fired up his '28 Harley, planted both feet firmly on the ground and used a stick to flop the clutch rocker over. He then power skated all the way to the dancehall. I guess people were tough back then.
