I am doing a mod to the front end of my GL1800 trike. I need to drill two 1/4 holes on the underside of the fairing, one hole on each side and under the front lights, hidden. I am a bit concerned that cracks might begin to form around the holes. Nothing will be attached to the holes, like a bolt or screw, no weight or tension. Should I be concerned about cracks or am I good to go? Also...any tips on drilling?
