Uhmm, some people prefer to call them "Ironheads" not Bowling Ball models....

The original suicide shifter was mounted on the left side of the gas tank with a foot operated clutch, you had to balance on your right foot at a stop while using the right hand to hold the brake and then take your left hand off the bar to shift. It could get sketchy in certain situations on a hill.
Lots of people modified them to a hand clutch/foot shift but kept the "Mousetrap" linkage.
The Knucklehead was one of the most beautiful creations in the mechanical world, had hydraulic lifters, overhead valves and if I remember my '46 had all of about 35 or 40 horsepower.
