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.
