Headlamp Adjusting Procedure Tools needed • Long, slender #1 Phillips screwdriver (for adjusters behind the rubber plugs) • #2 Phillips screwdriver (for the other adjuster screw) • 12-inch square of cardboard • Flat wall or garage door • Paper, tape, marker NOTE: All adjustments are very fine. You have to turn the screws A LOT to see changes in adjustment. This procedure is best done after dark, because you will need to do some test rides. Preparation 1. Set the bike on its center stand, 10 feet away from an unobstructed wall or garage door, and square to the wall or door. 2. Remove the front fairing cover and lower vent grille to gain access to the headlamp adjusters. 3. Idle the engine or connect a battery charger to the battery, to prevent battery drain.

With the lights on low beam, cover the right half of the lamp assembly with the cardboard square, so only the left bulb is shining on the wall. 2. Using a marker, mark the top of the left low beam on the wall (use paper taped to the wall if you don’t want to mark the wall itself) . 3. Move the cardboard so it blocks the left bulb, so only the right bulb is shining on the wall. 4. The top of the right low beam should be even with the mark you made for the left low beam. If it’s not, adjust by turning the screw behind the rubber plug at the top of the lamp assembly, using a long, slender #1 Phillips screwdriver. 5. Move the cardboard back and forth between the bulbs to verify that the low beams are at the same height. On high beam, the two hotspots should line up vertically. High Beam Vertical Adjustment 1. With the lights on high beam, note the position of the beams’ hot spots on the wall in relation to the mark you made in step 5 above. 2. Most owners complain about their low beams being too low on the roadway. To correct this, lower the high beams by turning the screw behind the rubber plug at the bottom of the headlamp assembly, using a long, slender #1 Phillips screwdriver. You can watch the high beam hot spot being lowered on the wall in relation to the mark you made. 3. Take a test ride. Get out on a dark street, and adjust the high beams using the dash knob until you like what you can see. Then switch to low beam and see how that looks. 4. Repeat these steps until you get the low beam pattern you want. Left/Right Adjustment 1. Back to the wall. Set the bike on its center stand at a distance of 25 feet from the wall and square to the wall. Center the front wheel. 2. Shine the high beams on the wall. 3. Step to the back of the bike, and level your eye with the center of the passenger backrest. Use the center of the backrest and the center of the windshield like a gunsight. The center of the hotspot of the high beam should hit the wall in this line. 4. Adjust by turning the uncovered screw at the bottom of the headlamp assembly, using a #2 Phillips screwdriver.
