Default Headlight adjustment

Anyone know the proper way to adjust the height of the head lamp. maybe being a certain distance away from a wall and seeing where the light hits? or something like that i just kinda eyeballed it. I think its a little too high but not sure.

I go out in the street at night and adjust the light so I am comfortable with the distance of the beam. I ride alot of freeway to and from work doing 70+ most of the time so I have mine raised up a little higher so I can see farther ahead.... There is a Proper way to adjust it in the manual, but I think it puts the hot-spot too close to the front wheel.

I have the service manual and I think it was 25' away from a wall and the middle of the beam should be 37" high.

Its in the owners and service manual. I pretty much adjust mine based on beam distance and angle when riding ( I pull over and adj. if needed). The angle changes ever so slightly when riding 2 up (like up in the face of passing drivers) so keep that in mind.

This is the proper way, but I think my manual says 35" up the wall.

35" to the top of the beam sounds about right, but the factory adjustment for my bike was TERRIBLE. Way too high. 5 to 10 feet in front of the bike, I was getting better illumination from the yellow turn signal/running lights than I was from the headlight.

What Iv'e alway s done, for bikes and cages, is to find a level parking lot, and park behind a car at about the same distance you would follow. Balance the bike upright with most of your weight on the seat, then adjust the headlight down so the top edge of the low beam is about tail-light high on the car in front. At least then, you aren't blinding anybody. Remember, the front end will come up under acceleration too, so the worst case is you blind oncoming traffic and they retaliate with their high beams, so neither of you can see.

Then see how it does illuminating the road in front of you. You will probably want to adjust it down even more. Low beam should intersect the road directly ahead of you. High beams shoud have the top of the beam parallel to the road, and the lower part of the high beam should still light the raod about 25 feet ahead of you.

I think it depends how high your lamp is mounted or sits above the pavement. A few inches below level ought to be about right.

I set so my brights light up the road well at night and run them bright during the day, then I dim them at night when in the city.

My factory setting pointed straight down to the ground. This is something every new owner should check upon delivery. I didn't realize mine was bad until the sun went down. Not good.

Same here. I rode for a week before I saw where the beam pointed - on the ground about six feet in front of me.

Most state standards call for 4" drop at 25 feet on the low beam setting.
If the headlamp center is 35" , then the hot spot would be aimed at 31" height on the wall.
E-Beams are similar , but easier because of the beam cutoff is so sharp.
If done properly , the high beam is automatically correct.
