I have a 91 gspd and I am replacing the headlight assembly. It is a pain in the ass. I got it in and had to fab a few plastic thingy majigers to hold the assembly to the mounting frame........blah blah blah. I want to position it correctly. I understand how to do it but, I would like to know where to line it up. Example: I am sitting on the bike, no stand or side stand, center of the light lines up with center of bike on a vertical plane. On a horizontal plane the center of the light is three feet off the ground when I am ten feet away from the wall. Does anyone have some numbers on this?
