Stop light To replace the stop and parking light bulb, unscrew the two screws (1, fig. 44.1) that secure the glass and remove glass. The bulb is of the banjo-type: press and rotate anti-clockwise to remove; fit the spare bulb by pressing and turning clockwise until it clicks (fig. 44.2). Refit the glass and tighten the screws (1). E Beam setting (fig. 45.1) When checking beam setting, put the motorcycle upright. Tyres should be inflated at the correct pressure and one person should be sitting astride the motorcycle, keeping it at right angles to its longitudinal axis. Place the motorcycle opposite a wall or a screen, 10 meters apart from it, then draw a horizontal line dictated by headlamp center and a vertical one in line with the longitudinal axis of motorcycle. If possible, perform this check in dim light. Switch on the low beam. The height of the light spot (measured at the upper limit between dark and lighted-up area) should not exceed 9/10th of the height from ground of headlamp center. Note The procedure described here is in compliance with the "Italian Standard" establishing the maximum height of the light beam. Owners in other countries will adapt said procedure to the provisions in force in their countries. The height of the light beam can be corrected using the screw (1, fig. 45.2) on the left side of the headlamp. Remove the left side guard of the instrument panel to expose the screw. Turn the screw clockwise to lower the beam, anticlockwise to raise it. fig. 44.2 56
