Got around to checking the alignment of my new LED OEM light and man was it off, way off. I followed the instructions (measure height to center of light with me on bike, put tape on wall 3 inches lower than that, 25 feet away, shock pressure on for my weight which is 0). The cut off for my low beam was about 6 inches below the mark on the wall! I adjusted my light up as far as it allows and the low beam cut off is still about 1/2 inch lower than it should be. I know XC headlight adjustment is different than the XR's so I don't know if it is a bike specific thing or if my headlight is off from the factory buy a possible heads up for you XR guys.
