(See the following section for an explanation of the ignition circuit cut-off system.) EWA10241 this system regularly and have a Yamaha dealer repair it if it does not function properly. 4 NOTICE The EXUP system has been set and extensively tested at the Yamaha factory. Changing these settings without sufficient technical knowledge may result in poor performance of or damage to the engine.
