Hi. Im a new owner of a 2013 Street triple r and on adjusting the rear shock i undid the red nut around the screwdriver slot by mistake. As oil started comming out i did it up quick but it still seems to be seeping out. I have been told that there is an o ring behind the nut that has probably split. What i would like to know is can it be topped up and a new o ring put in? The shock is a piggy back resovoir Kayaba. Thanks.
