Mornin',
I've got the Triumph out recently, and the driver's side door release sometimes doesn't release fully - you either need a good shove on the door to open it, or it doesn't close properly.
The catch in the lock mechanism on the back edge of the door isn't being retracted fully, so it leaves a small bit that gets in the way of the staple on the body.
Is there something I can adjust?
Cheers,
