Indeed those are very nice looking pieces. Very solid lockup, it would seem. Q: Have you perchance drilled the bottom of your slider so that both sides have an axle pinch bolt? Yamaha used this to tighten up their front ends. As well, they used a split collar (similar to these braces) on the upper triple where it clamped to the steerer tube of the lower clamp. The EX is really weak in that regard.
Most commercial braces have a spacing adjustment and this requires some careful setup. Best is to leave them slightly loose, then stroke spring-less forks through their travel taking note of any stiction, adjusting as needed. However, a lot of these went onto forks that were hashed and needed new bushings in the first place, so I suppose that some were indeed binding as a result of that wear and improper brace setup, thus, chatter.
As to the EX, fork tube diameter increased, but I have never measured the slider diameter for difference between generations.
I finally figured out why I like Ducatis: With their exhaust note and dry clutch, they sound almost like a Guzzi!
