Recall History (1 recall)

04V465000Apr 2005

FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY

ON CERTAIN MOTORCYCLES, A CONDITION OCCURS THAT COULD ALLOW PRESSURE TO BUILD UP IN THE FUEL TANK. ON FUEL INJECTED VEHICLES, THIS CONDITION COULD CAUSE FUEL TO SPRAY OUT UNEXPECTEDLY WHEN THE FUEL CAP IS REMOVED. ON CARBURETED VEHICLES, EXCESSIVE FUEL COULD BE TRANSFERRED TO THE CARBURETOR, WHICH WOULD EVENTUALLY ALLOW FUEL TO DRIP FROM THE AIR CLEANER.
