I was building a 58 flathead, 2 1/2" over springer front, ridged rear, suicide clutch, jocky shift. Never did get to finish it or ride it do to purchasing my home, some things just out weigh others. I've allways loved the idea! It would definately make it a riders bike and not just something anyone could hop on. The trick is of course what others have stated, is your at a stop on a hill, left foot on the clutch, right foot down, left hand on the shifter, right hand front brake and gas? Atleast with fuel injection you wont have to keep it running!
So if you do the suicide clutch, you pretty much have to do a jocky shift,,, to make it super trick,,,, left hand throttle, yah I'm a little demented that way!
