Former MTA chairman Peter Kalikow is ripping Gov. Cuomo for failing to adequately finance and support the city’s stressed mass transit system.

The real estate mogul and former Post publisher said Cuomo “has not done what he should be doing.”

He said current MTA boss Tom Prendergast, who headed the Long Island Rail Road division of the MTA during his tenure, is doing a “very good job.”

But he added that the MTA “shouldn’t have to go hat in hand and beg for capital money.”

“It’s not right. Cuomo is wrong. He’s nickled an dimed the MTA on the capital program,” Kalikow told The Post, in rare criticism of the governor from a former MTA chair.

He said while Albany has promised $8.3 billion toward in the $27 billion five-year capital plan, the state has handed over less than two billion dollars of the promised funds so far.

“They have not funded it properly,” Kalikow said. “If you get Prendergast the money needed, he could do the job.”

Kalikow, a Republican who is a delegate to next week’s GOP convention in Cleveland, was appointed to the MTA by former GOP Gov. George Pataki, serving as chair from 1998 to 2005.

But Kalikow also has been a booster of Cuomo.

He bucked his party’s candidate, Carl Paladino, and endorsed Cuomo for governor in 2010. He also has donated $65,715 to Cuomo’s campaign coffers.

During Kalikow’s tenure, the MTA started construction of the Second Avenue subway and extension of the No. 7 train, but also encountered a transit workers’ strike.

The MTA dismissed Kalikow’s criticism as off base.

“Never in the history of the MTA has there been a larger state investment in a Capital Program than the record $27 billion Gov. Cuomo secured – and no revision of history will change that,” said MTA spokeswoman Beth DeFalco.
