well as it turns out i didnt mount the preditor vertical anyway i went with something i used on a previous build worked pretty good. im putting this on what i believe is a 53 schwinn. i need a daily rider ive been riding my 212 roadmster like crazy but i want to keep it in nice shape so i figure to get this 99cc preditor a shot before the snow flies so whatch think?
