Try lubing the new cable. Also, check the routing between the cylinders and make sure the cable isn't touching anything hot. This is a known issue on your bike model. FWIW, my '13 V7 Stone had a defective clutch cable from the factory. It broke at the handlebar end, at the crimp fitting, after about 2000 mi. Before it separated completely, as individual wires came apart, the adjustment went off several times. The cable finally snapped in my driveway as I came back from a longish day-trip. Fortunately, I had purchased a spare a few weeks earlier, so I was up and running in a half hour or so. The original cable was replaced on warranty, but, to satisfy MG-USA, the dealer and I had to "pretend" that the dealer did the repair.
