                           WARNING
    Incorrect installation of the vehicle-down sensor
    could cause sudden loss of engine power. The
    rider could lose balance during certain riding situ-
    ations for an accident resulting in injury or death.
    Ensure that the vehicle-down sensor is held in
    place on the upper fairing bracket.
