11 pages, 4 figs.-- Physica A (in press).Recent studies on Brownian motors driven by colored non Gaussian noises have shown that the departure of the noise distribution from Gaussian behavior induces an enhancement of its current and efficiency. Here we discuss some new aspects of this phenomenon focusing in some analytical results based in an adiabatic approximation, and in the analysis of the long probability distribution tails' role.HSW acknowledges the partial support from ANPCyT, Argentine, and thanks to the European Commission for the award of a Marie Curie Chair at the Universidad de Cantabria, Spain.Peer reviewed
