Motorcycle Fairings are generally made of ABS plastic. So is standard ABS sewer pipe. Just like ABS pipe can be sealed together so can broken fairings. And the materials needed can be picked up at your local Lowes or Home Depot.
Just use ABS cleaner to clear the crack/joint. Then apply the ABS cement. Let it bond together and you are good to go.
This is an example of how to build a pre-equalized anchor with two bolts. I used short cord material (1x dbl. shoulder length sling) since we an extension was not necessary to avoid extensive rope friction over an edge or rock. This is a standard two bolts anchor that is also often called a “sports anchor”
