Singh, remove that slotted chrome plug ,and see if there is fork oil under it. If there is, there should not be, if you have the same front end as a C-5. If I remember correctly,there is another plug under that chrome one. I believe is has a 6mm allen head. see if it is loose.The top chrome slotted plug is decorative. The plug under it is the top plug on the fork. You can not remove it through the hole, but you can tighten or loosen it some through the hole. I think maybe that is where it is leaking from.
