The question of “how to check the headlight adjustment” was asked. So I guess some folks don’t have an owner’s manual or service manual. Or, might have a custom headlight, or whatever. You should still check with your local dealer for exact measurements if you don’t have a manual. This procedure should give you a very good baseline adjustment for just about any bike with a single headlight.
First, the basics: All adjustments are done on level ground. Use the “high beam” only while making adjustments. Bike should have the normal load that it carries, and standing straight up. The adjustment is very simple, so I’ll try not to over complicate it.
As for the adjusters on your bike, you will have to look at it to determine how to move them. There are several different types. Most are relativity simple and straight foreword. Again, check with your dealer or manual if your not sure.
The first measurement you need is the distance from the headlight to the taillight. Take that and multiply by.75, add 250, divide by E=MC2, subtract ½ and tighten the bolts. Did it work? If not, lets try the next method.
The garage door and driveway work good for this. Also masking tape. Measure 25 feet from the garage door. Mark the driveway at that spot. Measure the distance from the ground to the center of your headlight. Mark the door at that height, in a straight line from the mark on the driveway. Place the front axel over the mark on the driveway. Sit on the bike, stand it straight up and straight ahead, turn on the high beam. The mark on the door should be in the center of the main part of the beam. Adjust as necessary.
