A drunken motorcyclist who had just blown a red light slammed into a man crossing a Queens street early yesterday, leaving the unidentified pedestrian fighting for his life, authorities said.

The man had been crossing Steinway Street near Broadway in Astoria at 3:15 a.m. when a 2009 Yamaha ridden by José Salas, 30, sent him flying, cops said.

The pedestrian was listed as being in critical condition last night at Elmhurst Hospital.

Salas, who stayed at the scene, was arrested and charged with DWI, assault, criminal possession of a weapon and violating a traffic device, cops said.

Two unlicensed bikers who were accompanying him, Meto Adovic, 25, and Akira Rodriguez, 29, were arrested and charged with aggravated unlicensed operation of a motor vehicle.
