EBU00409 EBU00412 Headlight beam adjustment CAUTION: It is advisable to have a Yamaha dealer make this adjustment. 1. Vertical adjustment: To raise the beam, turn the adjusting screw clockwise. To lower the beam, turn the screw counterclockwise. 1 Troubleshooting Although Yamaha machines receive a rigid inspection before shipment from the factory, trouble may occur during operation. Any problem in the fuel, compression, or ignition systems can cause poor starting and loss of power. The troubleshooting chart describes a quick, easy procedure for making checks. If your machine requires any repair, take it to a Yamaha dealer. The skilled technicians at a Yamaha dealership have the tools, experience, and knowhow to properly service your machine. Use only genuine Yamaha parts on your machine. Imitation parts may look like Yamaha parts, but they are often inferior. Consequently, they have a shorter service life and can lead to expensive repair bills. 1. Adjusting screw (× 2) 8-35
