My leg bushings are in good shape.
My PFP bushing on one cart is good. The wear I've noticed on the other PFP bushing has been attributed to catching on a bur on the inside of the drainholes on the cart. Piston only runs through this on disassembly/assembly. Not in use.
Each set of Marzocchis show varying degrees of tolerance. Some the upper bushing is very tight on the leg, others it floats some more. I imagine varying degrees of tolerance in the coatings on the surfaces as well.
My forks aren't getting any more new anything after one of the PFP carts sucked up some alloy from the spring perch turning against a sharp edge on the preload spring clip. Constant contamination and visible wear/damage in one cart. I feel the fork action break down in around 5hrs ride time. Its not cost/time effective to continue changing oil at that rate.
No crossover found for the PFP. If I was in the suspension business, I'd look at having a complete new IFP designed which doesn't catch air around the outer edge, and accomodates a freely available (and cheap) bushing.
