We used to do that years ago with our Bultaco’s and our 4 wheelers. We’re screw 1/2” long sheet metal screws into the lugs on the 4 wheelers and put elevator leg bolts sharpened to a point on the Bultaco motorcycles from the inside out. We’re set up traffic cones on the frozen lake and get about 20 guys out on the weekends for some great racing. I miss those days but not the agony of the wrecks !!
