This is the lay out of a simple two cut fairing. The top is to the left. Drill the holes first then cut the slits. Overlap the side cuts to the dotted lines and clamp while poking the holes for the zip ties. Do the top cuts last. The center circle should be at the height of the handlebars. Cut the opening for the head tube and brake cable. Zip tie the lower part of the fairing to the down tube. The center circle is large enough to cut an opening for a headlight.
