Harley-Davidson is recalling more than 3,300 FXDL Dyna Low Rider bikes because engine vibration can turn the switches from “on” to “accessory.”
The recall covers motorcycles from the 2014 1/2 model year. If the motorcycles have been modified to rev higher than 5,600 rpms, an engine mount bracket can vibrate excessively, causing the problem.
If the switch goes to “accessory,” the engine can shut off while being driven and potentially cause a crash. The company said there have been no crashes or injuries reported from the problem.
Dealers will replace the bracket assembly and ignition switch knob free of charge. Harley began notifying owners in late July.
Harley said in documents posted Friday by the U.S. National Highway Traffic Safety Administration that the motorcycles are limited at the factory to 5,600 rpms, but Harley offers performance calibrations that let the engine rev higher than the limit. If the bikes hit 5,800 rpms, the top engine mount bracket can vibrate too much and cause the ignition switches to malfunction.
The company said it began looking into the problem after its service department discovered that an ignition switch slipped out of the “on” position in testing. The company found four warranty claims and complaints about the problem, all in bikes with non-Harley exhaust systems.
