Hi mikea, it would help if you'd post your bike's make and year in your profile on the signature line, without knowing that I don't know if you're talking about the round vent as on the early 'Wings or the rectangular vent of the later ones. Cutting a vent hole is pretty easy, cover the area with masking tape, draw your cut, drill a hole in the waste area big enough to get a sabersaw blade stated and cut it out just inside the line. Finish up by sanding the edges of the hole to remove all saw marks and scratches, radius the edges of the hole a bit with some sandpaper. It's best to take the windshield off, less chance of error that way but you can do it on the bike.
If you're cutting a rectangular hole drill a small hole at each corner of the hole before cutting. Leaveradiused corners, don't leave the corners square, that can initiate cracking. If you need a round hole, use a hole saw of the correct size or just cut it out after marking with a compass on the taped plastic. Don't do any drilling or cutting in the cold, warm plastic cuts with less chance of cracking.
