AID FOR CITY CITED
Mayor Koch, with Governor Cuomo at his side, said yesterday that New York City would get an ''acceptable'' share of money from a proposed $1.25 billion bond issue and that he would campaign for its passage this fall. On Thursday, the Legislature ratified an agreement on how the money from the proposed bond issue would be spent. The money would be used to reconstruct and expand roads, bridges and ports throughout the state. Mr. Koch, whose support the Governor's aides said was crucial, had insisted the city receive a ''fair share'' of the bond issue. At one point, he had said the 25 percent share offered the city by Mr. Cuomo was insufficient.
