My friend Corinne, is now riding her new motorized bicycle even though she only has one hand. I made her a locking right hand clutch handle out of parts I found at the hardware store. My design is an improvment over the stock handle, because it holds the lever open slightly more than the stock handle. This results in less drag from the clutch.
This is how we machine a part in the ghetto. This was the hardest part. I had to machine the pin to be thin enough so the lever would close. There was very little room for error, and took me 3 tries to get one right
Now it operates exactly like the stock lever
