Issue: On certain scooters, the cylinder head nuts may not have been tightened properly and could loosen. If this happens, the cylinder head gasket can fail. This could prevent the engine from starting, or could cause the engine to stall. Safety Risk: A sudden loss of engine power could increase the risk of a crash. Corrective Actions: Yamaha will notify owners by mail and instruct you to take your scooter to a dealer to replace the head gasket. To reduce the safety risk, Yamaha recommends that you should avoid riding your scooter until the recall repairs have been completed, except to take it to the dealer for this repair.
