It has shox which he believes to be original and thinks were made by Showa
They are leaking like my bank account and he would really like to sort them by replacing the seals at the bottom of the damper rods. He thinks they might be nitrogen filled? After a quick looksie I can't see any filling valves, nor can I see any obvious way of removing the damper rod seals.
Anyone have any experience of servicing/repairing these shocks?
