Yamaha is recalling 9,600 model year 2006 and 2007 CP250 and model year 2005-2007 YP400 motorcycles becauase the engines could stall and be difficult to restart because the wire terminals in the fuel pump wire coupler have corroded. Water can enter from the main wire harness end and run through the harness to the fuel pump coupler.
If the water remains in the coupler for an extended period of time, the terminals can become corroded, which can prevent the fuel pump from operating properly. If this corrosion affects fuel pump operation while the scooter is being ridden, there could be a crash resulting in injury or death.
Dealers will install a sub-harness designed to allow any water between the wire harness and the fuel pump to drain out before it reaches the fuel pump. The dealer will also inspect the connectors. If either the main wire harness connector or the fuel pump connectors is already corroded, the corresponding assembly(ies) will also be replaced.
The recall began May 1. Owners may contact Yamaha at (800) 962-7926.
