IMPROPER FUEL TANK WELDS PLUGGED THE FUEL FILTER WITH DEBRIS. DISCOVERED THE ZINC FLAKES UPON INSPECTION OF THE FUEL TANK. 425 MILES ON THE MOTORCYCLE AND LESS THAN 10 GALLONS OF GAS THROUGH THE TANK. UNLIKE AUTOMOBILES, WHEN A MOTORCYCLE FUEL SYSTEM IS COMPROMISED, A LOSS OF POWER CAN BE CATASTROPHIC TO THE RIDER. UNWILLING TO RISK MY SAFETY, INCLUDING DEATH, I WAS PROACTIVE IN MY INVESTIGATION OF THIS OWNER AND DEALER KNOWN ISSUE, AND STARTED MY OWN MAINTENANCE PLAN TO PREVENT AN UNINTENTIONAL DANGEROUS LOSS OF POWER, WHICH MIGHT OCCUR ON THE INTERSTATE HIGHWAY SYSTEM AT 70 MPH.

VEHICLE WAS IN MOTION ON AN INTERSTATE HIGHWAY AT APPROXIMATELY 70 MILES AN HOUR, IN TRAFFIC, WHEN ENGINE SUDDENLY STOPPED RECEIVING ADEQUATE FUEL. REVS WERE LIMITED TO 4K AND INCOMING TRAFFIC BEHIND ME NEARLY CAUSED A COLLISION, DUE TO MY SUDDEN LOSS OF SPEED WITHOUT BRAKE LIGHTS. UPON TAKING TO SHOP, A WHITE PASTE-LIKE SUBSTANCE WAS FOUND COVERING SOME OF THE KEY WELDS INSIDE THE GAS TANK. THIS SUBSTANCE FLAKES OFF AND CLOGS THE FUEL FILTER. IN MY CASE, THIS HAPPENED WITHIN THE FIRST 4,000 MILES. THIS APPEARS TO BE A MANUFACTURING ERROR IN WHICH THE HEAT OF WELDING CAUSES A SPECIAL GAS TANK LINING TO CORRODE AND FLAKE OFF. UNLESS PROACTIVE MEASURES ARE TAKEN BY THE CUSTOMER BEFOREHAND - IDEALLY AT OR NEAR THE TIME OF PURCHASE - THE MANUFACTURING PROCESS OF THIS BIKE MAKES IT *UNSAFE TO RIDE*, AS THIS SITUATION CAN OCCUR AT ANY MOMENT AND IS BEYOND CONTROL OF THE RIDER. PREVENTION AND/OR REPAIR FOR THIS DEFECT REQUIRES AN UNDUE AMOUNT OF INVESTMENT ON THE PART OF THE OWNER IN ORDER TO MAINTAIN THEIR OWN SAFETY. THE ATTACHED IMAGE IS TAKEN FROM THE FUEL FILTER HOLE ON THE UNDERSIDE OF THE GAS TANK, AND SHOWS THE INNER SURFACE OF THE TANK ITSELF. IN THE IMAGE YOU CAN CLEARLY SEE THEY WHITE "PASTE-LIKE" SUBSTANCE SURROUNDING THE TANK'S WELDS, AND SEE HOW IT IS STREAMING OFF DUE TO EXPOSURE TO GASOLINE. THE NHTSA SHOULD CONSIDER OFFICIALLY INVESTIGATING THIS PROBLEM AS IT IS CLEARLY DUE TO INSUFFICIENT MANUFACTURING PROCEDURES, AND BUYERS SHOULD CONSIDER THEIR OWN SAFETY BEFORE PURCHASING THIS MOTORCYCLE. UNTIL THIS SITUATION IS RESOLVED VIA RECALL AND CORRECTION OF MANUFACTURING PROCEDURES, THIS MOTORCYCLE SHOULD BE CONSIDERED UNSAFE.

WHILE RIDING ON HIGHWAY AT HIGHWAY SPEED, MOTORCYCLE SUDDENLY CUT POWER AND BEGAN STUTTERING. WOULD NO LONGER MAINTAIN SPEED AND WAS BOGGING DOWN, EVENTUALLY STOPPING COMPLETELY. SYMPTOMS EXACTLY THE SAME AS RUNNING OUT OF GAS, YET HAD PLENTY OF GAS IN THE TANK. AFTER STOPPING AND TURNING OFF THE MOTORCYCLE FOR 15 SECONDS, IT STARTED BACK UP AND CONTINUED TO JUST HAVE IT RECUR A RANDOM NUMBER OF MILES LATER. OTHER USERS OF THIS SAME MOTORCYCLE HAVE REPORTED THAT MATERIAL USED IN MANUFACTURING THE TANK IS FLAKING OFF WITH AROUND 3000 MILES AND CLOGGING THE FUEL INTAKE. STOPPING THE BIKE RELIEVES SUCTION AND UNCLOGS THE INTAKE FOR A RANDOM AMOUNT OF TIME UNTIL THE MATERIAL FINDS IT'S WAY BACK TO THE INTAKE. *TR

The Office of Defects Investigation (ODI) opened this Preliminary Evaluation (PE) on August 10th, 2020 to investigate 26 reports of stalling due to clogged fuel filters on model year (MY) 2018 - 2020 Honda African Twin (CRF 1000 - 1100) motorcycles.Many of the owners allege the subject vehicle would suddenly stall while riding. Although the stalling speeds varied, most consumers allege the stalling occurred at highway speeds. This stalling condition is caused by clogged fuel filters. The subject vehicle fuel filters become contaminated with zinc-oxide (corrosion). The corrosion is coming from the inside of the fuel tank, along the end seam of a joint weld. The corrosion clogs the fuel filter, restricts fuel flow to the engine, and subsequently causes a sudden engine stall.During complainant interviews, ODI learned the bikes can sometimes be restarted after the initial stall. However, several consumers described this restart as causing a false sense of security.After restarting the bike and attempting to accelerate/merge into traffic, the bike quickly stalls again. This time the rider is placed in the middle of traffic, potentially causing a crash or risk of injury.On October 9, 2020, ODI received Honda?s Information Request (IR) response and learned that Honda was aware of 36 complaints, 87 field reports and 83 warranty claims of stalling related to clogged fuel filters. There were no claims of crashes or property damage associated with the alleged defect on the subject motorcycles. Additionally, Honda initiated three different modifications or changes to the fuel tank during production. On March 11, 2020, Honda released a customer satisfaction campaign to remove the zinc oxide that can contaminate the fuel pump filter, causing reduction of fuel flow. The part numbers for the fuel tank did not change after the implementation of the zinc oxide removal process. The process improvement was a running-change and no parts were withdrawn from production. On October 5, 2020 Honda added a new maximum contamination specification. This new specification was initiated to limit the contamination from the tank supplier. The tank supplier improved the cleaning process to meet the low contamination limit.Discussions and analysis of the data between ODI and Honda resulted in the manufacturer recalling certain 2018-2019 Africa Twin Adventure Sports (CRF1000L) and 2020 Africa Twin Adventure Sports (CRF1100L) motorcycles.Contaminants inside the fuel tank may cause the fuel filter to clog, resulting in an engine stall, and increasing the risk of a crash.ODI is closing this PE with Honda?s voluntary safety recall 20V-797. With the recall action taken by Honda, this investigation is closed, as further use of agency resources does not appear to be warranted.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist on other models or MY vehicles outside of the recall scope. The agency reserves the right to take further action if warranted by the circumstances.

The part numbers for the fuel tank did not change after the implementation of the zinc oxide removal process. The process improvement was a running-change and no parts were withdrawn from production. On October 5, 2020 Honda added a new maximum contamination specification. This new specification was initiated to limit the contamination from the tank supplier. The tank supplier improved the cleaning process to meet the low contamination limit.Discussions and analysis of the data between ODI and Honda resulted in the manufacturer recalling certain 2018-2019 Africa Twin Adventure Sports (CRF1000L) and 2020 Africa Twin Adventure Sports (CRF1100L) motorcycles.Contaminants inside the fuel tank may cause the fuel filter to clog, resulting in an engine stall, and increasing the risk of a crash.ODI is closing this PE with Honda?s voluntary safety recall 20V-797. With the recall action taken by Honda, this investigation is closed, as further use of agency resources does not appear to be warranted.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist on other models or MY vehicles outside of the recall scope. The agency reserves the right to take further action if warranted by the circumstances.

The Office of Defects Investigation (ODI) opened this Preliminary Evaluation (PE) on August 10th, 2020 to investigate 26 reports of stalling due to clogged fuel filters on model year (MY) 2018 - 2020 Honda African Twin (CRF 1000 - 1100) motorcycles.Many of the owners allege the subject vehicle would suddenly stall while riding. Although the stalling speeds varied, most consumers allege the stalling occurred at highway speeds. This stalling condition is caused by clogged fuel filters. The subject vehicle fuel filters become contaminated with zinc-oxide (corrosion). The corrosion is coming from the inside of the fuel tank, along the end seam of a joint weld. The corrosion clogs the fuel filter, restricts fuel flow to the engine, and subsequently causes a sudden engine stall.During complainant interviews, ODI learned the bikes can sometimes be restarted after the initial stall. However, several consumers described this restart as causing a false sense of security.After restarting the bike and attempting to accelerate/merge into traffic, the bike quickly stalls again. This time the rider is placed in the middle of traffic, potentially causing a crash or risk of injury.On October 9, 2020, ODI received Honda?s Information Request (IR) response and learned that Honda was aware of 36 complaints, 87 field reports and 83 warranty claims of stalling related to clogged fuel filters. There were no claims of crashes or property damage associated with the alleged defect on the subject motorcycles.
