Thanks for the quick response.
My forks seem to operate normally (i.e., like pogo sticks), so I don't think anything is bent. And I pinged another local Nuovo Falcone owner who is also a professional motorcycle mechanic, and she responded that her forks have the same issue.
I'll report back if we come up with an easy fix. But I suspect this will require disassembling the forks and replacing bits. Maybe replacing the lower rubber ring with a delrin or nylon piece that is less subject to distortion. I had planned to tear the forks down to install SR500 fork seals anyway.
