Title: RPM fork valves cleaning/flushing
Post by: jvb_ca on September 07, 2023, 03:10:51 PM
I am re-doing front fork seals on my 86 with 91 forks fitted with Randy's RPM valves etc. Leaky seals after a few years with these forks has me doing a rebuild....seals/bushing/sliders etc. My question is, what should I be using to flush out or clean the valves? The oil was stinky, as always, and a fair bit of crud in there. Cleaning tubes and legs is easy enough, but I want to flush out/clean the valves, but not sure if varsol, or spirits are good for these? Was there some sort of thread locker used in assembly? Or am I being to anal????
Any info muchly appreciated.
Oh, new brake pads and a good cleaning of calipers and discs are in order as well, as fork oil made a mess of left side.
Cheers...Jake

Pop the plastic seals off the outer edge and clean them with whatever you want. The rest of the parts are aluminum, brass, and stainless shims.
