«  Vibrola into agreement »

Hello

I also have an SG Deluxe 1971 equipped with a type Bigsby vibrato stamped Gibson.
I love this guitar as you describe so well has a look and sound of hell without mentioning its playability "easy" ...
My only concern is that when I use the vibrato it takes no longer agree, and I am obliged to practice pressure on the vibrato but in reverse to recover the initial tuning.
Then suddenly I do not use too much vibrato and it annoys me a bit (excuse me the term).
I'd like to ask your opinion if possible, or possibly that of your friend luthier.
Thank you in advance for your possible answer.

Musically.
