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 tt̅, where both production and decay are KK-parity non-conserving. We use, for the first time, the exclusion data for a tt̅ resonance
