well my frame must be a early super scramble,because the tubing is all 7/8 and from the looks of the pictures posted with the guy riding,that too looks all the same......:shrug:
i also notes when the big block is mounted in my bike frame just like the pictures. the sparkplug is off-set from the top frame rail,so the tip of the sparkplug and wire boot clears the frame. making it for easy to get to.
now does anybody have the power to convert black and white pictures into color. so i can tell what color the engine is...........:laugh:
