We investigate transport properties of a Hamiltonian system with two degrees of freedom. We found that, for a range of parameter values, transport is superdiffusive, and we numerically comfirmed that this is caused by stickiness of ballistic mode islands. We also note that a Poincare map of our system has properties similar to those of Levy flight.
