The following is perhaps one of the more interesting recalls to come across our desk, and it affects the 2014 Harley-Davidson Dyna Low Rider. It seems that if owners install “certain optional performance electronic control module calibrations” the bike’s ignition switch can go from “IGN” to “ACC”, thus causing the motorcycle to shutoff mid-operation.
The reason for this though is because the aftermarket ECU upgrade allows the 2014 Harley-Davidson Dyna Low Rider to rev its motor beyond the stock 5,600 rpm redline, where at 5,800 rpm a resonate frequency with the ignition switch occurs. Held at this frequency, the key can turn to the accessories position — a dangerous, if not fascinating, show of physics.
To remedy the situation, Harley-Davidson will notify affected owners, and Harley-Davidson dealers will replace the engine mount bracket assembly and ignition switch knob, free of charge. The recall is expected to begin by the end of July 2014.
The recall affects 3,361 FXDL motorcycles. Concerned owners may contact Harley-Davidson customer service at 1-800-258-2464; and as always, the NHTSA is also available at 1-888-327-4236 and safercar.gov.
