NHTSA recall 99V067000

What's wrong: This feature is designed to prevent the fuel injection system from continuing to pump fuel if the motorcycle falls down, by shutting off the ignition and fuel injection pump. During battery maintenance, the vehicle-down sensor can be dislodged from its normal mounted position. If the sensor is out of position, the motorcycle may not start or may stall during certain driving maneuvers.

Why it matters: If the sensor is not correctly installed, the engine can crank but not start or the engine could stop during certain riding situations, like leaning over in a turn. Sudden loss of engine power could cause the operator to lose their balance resulting in injury or death.

The fix: Dealers will inspect for proper mounting of the sensor and re-install if it is not in the correct position. Dealers will also affix to the motorcycle frame, a warning label that provides instructions on repositioning the vehicle-down sensor after servicing the battery.
