I have had my front forks revalved, springed and seals replaced and one still leaks. I took it back and again it leaks after a few rides. I know I need to take it in for a permanent fix but for now I am going on a long ride in baja this weekend and was hoping someone could explain how to "top up" the fork oil. Is it hard? What measurements do I need to do and what shouldnt I do. Thnaks in advance guys.
