How do you release a seat on a 1982 Nighthawk 450?

Unlock the helmet lock so that the shackle falls loose. Stand behind the bike. With your right hand, pull the shackle towards you. With you left hand, feel around the same area on the left side of the seat and you'll find a 2" trigger. Pull the shackle and the trigger towards you while at the same time lifting up on the seat with your thumbs. Once the rear of the seat has cleared the locks, slide the seat up and back and it will separate from the bike.
