Mount the strip on the bars so that it sits horizontally. Position the fairing at the desired height. Now punch small holes for two or more TyRaps to go around the steel strip which are sufficient. The lower mount can be tricky if you have suspension forks. I tried taping the lower edge to the sliders but that let go on a particularly wet, cold and muddy ride.
Rigid forks are an easier option.
I just use the duct tape to secure the lower edge to the fork blade. Again a bracket from the fork crown to the fairing would be better. The lower outside edges were taped so that they were pulled together and supported by a strip of plastic. This reduced frontal area and stabilised the lower section. Very well is the answer.
