  We study the rare kaon decays in the framework of general SUSY models. Unlike
the results in the literature, we find the contributions from the gluino
exchange to the branching ratio of $K^+\to \pi^+ \nu \bar{\nu}$ can reach the
central value ($\sim 1.5 \times 10^{-10}$) of the new E787 data while the
predicted value of standard model is less than $10^{-10}$. We also find that
the same effects also enhance the decays of $K_{L}\to \pi^0 \nu \bar{\nu}$,
$K_L\to\pi^0e^{+} e^{-}$ and $K_L\to\mu^+ \mu^-$.
