I've tried to get these original Paioli forks working.
My racing style is very heavy on the front end, and I must just be pushing them outside their working range.
I had spotters at the side of the track at Brands to see if they could see what was causing the bike to judder so violently.
"Well I saw daylight under your front wheel it was pattering that much!" was one reply - so I think it's time to try and source some alternative. The forks are 50mm at the top yoke and 53mm at the bottom yoke, if you know or have anything that are these dimensions let me know.
