We present preliminary results from a search for inclusive charmless B {yields} KX decays. These decays occur dominantly via one-loop b {yields} s penguin transitions, and can provide useful information about these processes. Using a sample of 288.5 fb{sup -1} collected with the BABAR detector at the PEP-II asymmetric-energy e{sup +}e{sup -} B Factory at SLAC, we search for high-energy kaons recoiling against fully reconstructed B decays. We measure the partial branching fractions for kaons with momentum p*(K) > 2.34 GeV in the B rest frame, and obtain (in units of 10{sup -6}): {Beta}(B {yields} K{sup +}X, p* > 2.34 GeV) = 1.96{sub -34}{sup +37}(stat.){sub -30}{sup +31}(syst.) and {Beta}(B {yields} K{sup 0}X, p* > 2.34 GeV) = 154{sub -48}{sup +55}(stat.){sub -41}{sup +55}(syst.) (< 266 at 90% C.L.).
