  In five-dimensional universal extra-dimensional models compactified on an
$S^1/Z_2$ orbifold four-dimensional kinetic terms are allowed at the two fixed
points. If these terms are unequal then Kaluza-Klein (KK) parity is broken.
Within such a framework we consider resonant production of the n = 1 KK-gluon
at the Large Hadron Collider and its subsequent decay to $t\bar{t}$, where both
production and decay are KK-parity non-conserving. We use, for the first time,
the exclusion data for a $t\bar{t}$ resonance obtained by the ATLAS
collaboration to limit the mass ranges of quark and gluon excitations of the
KK-parity-violating model which are found to be in the ballpark of 900 GeV.
