Harley-Davidson is joining their ranks with a new repair campaign on some of its bikes, but for a somewhat different reason: some examples of one model might be vibrating too much.

According to Harley’s recall filing with the National Highway Traffic Safety Administration, the problem affects 3,361 units of the 2014.5 FXDL Dyna Low Rider built from January 6, 2014, through June 19, 2014. The report states that “certain optional performance electronic control module calibrations” may cause enough engine vibrations to move the ignition switch from the “IGN” on position to the “ACC” position where only the accessories work. This movement would shut off the engine.

The full defect notice goes into more detail explaining that the engine mount bracket on these models has a resonant frequency that happens around 5,800 rpm. At this point, it begins vibrating the ignition switch and can cause it to change position. The stock bikes only allow engine speeds up to 5,600 rpm, according to the report, but the company offers an option to increase the limit further.

To fix the problem, Harley is replacing the “engine mount bracket assembly and ignition switch knob,” on all models, even those that still have the 5,600-rpm limiter in place, according to the notice.
