We take as initial data a KNBH with mass $M$, angular momentum to mass ratio $a$ and charge $Q$. Evolutions are performed to scan this parameter space within the intervals $0\\le a/M\\le 0.994$ and $0\\le Q/M\\le 0.996$, corresponding to an extremality parameter $a/a_{\\rm max}$ ($a_{\\rm max} \\equiv \\sqrt{M^2-Q^2}$) ranging from $0$ to $0.995$. These KNBHs are evolved, together with a small bar-mode perturbation, up to a time of order $120M$.
