Hi Guys, I am trying to get the anti-dive on my '86 VF500 F working as it should since in a couple of old magazine road tests it is reported to help noticeably. The main question I need help with is the coupling of the piston in the anti-dive assembly to the caliper which activates it. On my bike the hole on the piston activating shaft is about 1/2 inch in diameter and the bolt which goes through it from the caliper has a diameter of 1/4 inch and thus is not coupled to the piston. I'v closely examined Honda micro-fisches and have not been able to find the bushing. What I'm wondering is, is the bushing metal, hard rubber or what? It should be easy to fabricate once I know what it is made of. Also, the piston itself is very stiff in the bore. Is this the way it should be? The FSM gives no guidance on this. Thanks in advance!

Not a Honda, but I had to rebuild the anti-dive units on 84 Kawasaki Ninja. In short, parts are almost non-existent for the Ninja, but a cottage industry sprung up and a few are made to get them working again. The Hondas, I don't know. The main issue was they get REALLY dirty inside and need cleaned out. Some Ninja owners claimed that was enough to get them working again. Both the Ninja and Honda units were not made to be serviced, so its a real challenge to figure some stuff out. The internals in the Ninja are pot metal, springs and O-rings. I recommend having a set of calipers on hand when you pull them apart and check out McMaster-Carr. That place carries everything. You may be able to get replacements that way. BZ
