Frank Patti, 26, of West Islip ... was riding west on the unregistered 2006 Kawasaki bike when he saw the two officers parked at a service station, according to a police report. "Patti looked at the officers, raised his middle finger in their direction, brought the motorcycle up onto the back wheel, a maneuver often referred to as a 'wheelie,' and took off southbound at a high rate of speed," the report said. "He dangerously weaved in and out of traffic, changing lanes erratically. At Great Neck Road and Oak Street, he executed another wheelie and continued southbound."
