Verdict · NHTSA data

Defect

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.

Consequence

THESE SITUATIONS COULD CAUSE SERIOUS PERSONAL INJURY OR CREATE A FIRE HAZARD FOR PERSONS OR PROPERTY ON OR NEAR THE MOTORCYCLE.

Remedy

DEALERS WILL TEST EACH CANISTER FOR BLOCKAGE, THEN REPLACE AS NECESSARY. THE RECALL BEGAN NOVEMBER 4, 2004. OWNERS SHOULD CONTACT HARLEY-DAVIDSON AT 1-414-343-4056.
