The Cometic copper head gasket for 1987–1990 Kawasaki ZX750 Ninja is specified for a 69mm bore at .010" thickness and provides a durable sealing surface for head applications. The gasket’s construction helps conform load distribution across the sealing area, requires less clamp load, and is intended as a direct replacement to preserve bore integrity without needing additional sealants or re-torquing during reassembly.
