We lightened the fork valving a little, but this made it worse because the forks used more stroke and the perches hit the oil more frequently.

So we went firmer on the fork. This reduced comfort a little overall, but kept the perches out of the oil more often and therefore reduced the frequency of the spike in damping.

We then removed the Pro Perches and fitted a single sided Huck Valve. My tester has not asked to try the Pro Perches again since.

I did speak with JB about his perches and explained the problems we were facing. He suggested a lighter shim stack on the perch, but we never got around to trying it.
Awesome, thanks for the update!!!!
