VEHICLE: 2006DUCATI MONSTER S2R 1000(NOT LISTED IN THE FOLLOWING LIST). WITHIN THE PAST 6 MONTHS, THE STOCK PLASTIC TANK ON MY MOTORCYCLE IS EXPANDING AND DEFORMING. THE TANK NO LONGER SITS CORRECTLY ON THE FRAME, THE HANDLE BARS HIT THE TANK PREVENTING FULL RANGE OF MOTION. ALSO THE HOLD-DOWN LATCH IS PRESSED AGAINST THE IGNITION SWITCH PREVENTING PROPER REMOVAL TO ACCESS THE UNDER TANK COMPONENTS, BATTERY, AIR FILTER. I HAVE NOT MODIFIED MY MOTORCYCLE, NOR IT'S FUEL SYSTEM OR FUEL PUMP, LOCATED INSIDE THE TANK. I TOOK MY BIKE TO AN AUTHORIZED DEALER WHO SUBMITTED A CLAIM TO DUCATI NORTH AMERICA, AND WAS DENIED A REPLACEMENT. NO REASON WAS GIVEN. I HAVE THIS DOCUMENTED ON A SERVICE RECEIPT. I AM CONCERNED ABOUT THE SAFETY OF THE BIKE. NOT ONLY DOES THE HANDLE BARS PREVENT PROPER TURNING RADIUS, BUT THE LOCK CAN NO LONGER ENGAGE. FURTHERMORE, THE FUEL PUMP FLANGE IS LOCATED DIRECTLY ABOVE AN EXHAUST HEADER, SHOULD THE WARPAGE BREAK THE SEAL AROUND THE PUMP FLANGE, GASOLINE WOULD LAND ON THE HOT PIPE. *TR

1PE10045 · Fuel Leak At Pump/tank Interface
Opened Nov 4, 2010 · Closed Feb 28, 2011
Status: closed (inferred from source dates) · Fuel System, Gasoline:storage:tank Assembly
After opening this PE, we met with subject owners, dealers, and Ducati North America personnel.We learned that the subject leakage is limited to the Multistrada line alone and is unrelated to composite fuel tank deformation.Rather it stems from the inability of the original sealing O-ring to conform to the tank's relatively rough sealing surface.Recall 11V-020 provides a new X section O-ring to address the Multistrada issue and with that recall, this PE is closed for the Multistrada.Meanwhile, unlike the Multistrada, the Monster line fails to exhibit a current safety defect trend and, on that basis, this PE is closed for those models as well.
