I bought a rear corbin seat with the backrest over the winter. It would pop on and off no problem. Yesterday my wife and I went for a ride and seems to have jammed on the bike. I tried to turn the key and push down on the seat to release it and it did not work. What has me is as you wiggle the key the backrest is moving and it is very hard to move the key. Is there any way to remove the rear inner fairing from the bottom to get to the latch. There is a hat in the tail section so I really can't see the latch. Thanks for the help
