  The semileptonic kaon decays $K_{l2\gamma}$ and $K_{l3}$ are considered. We
use the most general forms of the matrix elements for these decays. Additional
terms could arise as a result of new tensor interactions between quarks and
leptons. Such terms have been detected in a recent experiments. The high
precision experiments at DA$\Phi$NE may be ideal to confirm these results.
