The depth screw underneath the block sets the maximum depth of how far in the bar goes before it catches the retaining spring. The spring itself is not adjustable. If you back out the depth screw a bit then you may be able to insert the bar a little deeper (past the spring), but it won't necessarily latch into place.
I've put a few trem bars into a big vise and bent them for a smaller/wider angle - this may be the way to go if the above doesn't work. Make sure you tape or wrap the bar to avoid marring the finish when it's in the vise.
FWIW, I've also noticed that the bar on the Majesty feels almost as if it is in a different location (in/out) compared to my regular JP6s and JP11.
