about weight

Dear fluka experts,
      When I calculate the neutron production by the reaction of proton
beam-Tungsten, where the Beryllium reflecting layer wrapping the
Tungsten target, I find the a few neutron weights obtained by WTRACK are
great than 1 in case of no any variance reduction techniques being used.
Can the producing-particle weights be not 1 without variance reduction
techniques? Are my results possible?
Thanks very much!
