Adjust headlights on 2005 gl 1800

Post by warfelr »

I had to replace the adjustment motor and since I have all the plastic off I though I would check and adjust my headlights. I know how l am planning to do it but it would be nice to hear how others did it.

I'm still waiting for the part so I though I would think through the adjustment part. Thanks for any feedback or ideas

Proper headlamp aim is achieved by adjusting the upper(high) beams.
Bike needs to be on a level floor, standing upright, loaded as you normally ride. (re, 1up-you for most), with pre load set as you ride 1up, placed 25' from a wall to the headlamp lens in front of the upper beam. I would suggest the auto adjust dial be set in the middle position for this aiming.
Measure the distance from the floor up to the center of the upper beam bulbs. Mark this height on the wall and draw a horizontal line at this height.
Sight a point on the wall that is on the centerline of the bike. Draw a vertical line on the wall placed on this center line.
turn on the upper beams.
Cover one of the headlamps.
Use the manual adjusters accessed under the front of the fairing.
Adjust the vertical until the hot spot of the upper beam bulb is just under the horizontal line on the wall.
Adjust the horizontal until the upper beam hot spot is just to the right of the vertical line on the wall.
Cover the headlamp just completed, and repeat procedure on the other headlamp.
Make a small mark on the auto adjust panel so you can return to the 1up setting.
Now have both headlamps uncovered and have the usual passenger you carry sit on the bike w/you, set the preload for 2up, and dial in the auto adjust dial for proper aim and mark that position on the panel by the dial. You can repeat this for loaded 1up, loaded 2up, trailer, etc.
You get what you get for low beam aim depending on how good the headlamp design was to start with!
