Kelly, Kuhn and Osthus conjectured that for any @?=4 and the smallest number k=3 that does not divide @?, any large enough oriented graph G with @d^+(G),@d^-(G)=@?|V(G)|/k@?+1 contains a directed cycle of length @?. We prove this conjecture asymptotically for the case when @? is large enough compared to k and k=7. The case when k@?6 was already settled asymptotically by Kelly, Kuhn and Osthus.
