⚠ Safety Recalls (4)
CERTAIN SOFTAIL MOTORCYCLES FAIL TO COMPLY WITH THE REQUIREMENTS OF PART 567, 'CERTIFICATION.' THE VIN/CERTIFICATION LABEL CONTAINS INCORRECT TIRE SIZE AND INFLATION PRESSURES FOR THE FRONT WHEEL. THE LABEL STATES THE TIRE SIZE IS MT90B21 AND THE INFLATION PRESSURE AS 30 PSI, WHEREAS THE CORRECT TIRE SIZE IS MT90B16, AND THE CORRECT INFLATION PRESSURE IS 36 PSI.
Risk: THE CERTIFICATION LABEL IS INCORRECT GIVING IMPROPER INFORMATION.
Remedy: HARLEY- DAVIDSON WILL MAIL INSTRUCTIONS ALONG WITH CORRECTED FEDERAL CERTIFICATION LABEL. IF AN OWNER SO DESIRES, A DEALER CAN INSTALL THE LABEL FOR THEM. THE RECALL BEGAN ON JUNE 6, 2005. OWNERS MAY CONTACT HARLEY-DAVIDSON AT 1-414-343-4056.
CERTAIN MOTORCYCLES MAY HAVE BEEN PRODUCED WITH DEFECTIVE FUEL SHUT-OFF VALVES. THE FUNCTIONALITY OF THE 'ON' POSITION AND THE 'RESERVE' POSITION OF THE VALVE MAY HAVE BEEN REVERSED.
Risk: IF THE BIKE WERE OPERATING WITH THE VALVE IN THE 'ON' POSITION, THE BIKE COULD RUN OUT OF FUEL, THE EXPECTED FUEL RESERVE WILL NOT BE AVAILABLE. THIS COULD LEAD TO THE DRIVER RUNNING OUT OF GAS WITHOUT WARNING, INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL INSPECT THE FUEL VALVE AND REPLACE IT, IF NECESSARY. THE RECALL BEGAN FEBRUARY 7, 2005. OWNERS SHOULD CONTACT HARLEY-DAVIDSON AT 1-414-342-4080.
CERTAIN FUEL SHUT-OFF VALVES USED AS REPLACEMENT EQUIPMENT, P/NOS 61338-02, 62169-02A, 61338-94D, AND 62169-95C FOR USE ON CERTAIN 2005 CARBURETED SPORTSTERS, DYNA, SOFTAIL, AND TOURING MODEL MOTORCYCLES. THESE VALVES MAY HAVE BEEN PRODUCED WITH THE FUNCTIONALITY OF THE 'ON' POSITION AND THE 'RESERVE' POSITION OF THE VALVE MAY HAVE BEEN REVERSED.
Risk: IF THE BIKE WERE OPERATING WITH THE VALVE IN THE 'ON' POSITION, THE BIKE COULD RUN OUT OF FUEL, THE EXPECTED FUEL RESERVE WILL NOT BE AVAILABLE. THIS COULD LEAD TO THE DRIVER RUNNING OUT OF GAS WITHOUT WARNING, INCREASING THE RISK OF A CRASH.

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.
Risk: 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.
