I just got a service kit from sr Suntour for my Aion 35. It comes with everything I need for the service but when I try to find the amount of oil to put in, all I can find is that none of their forks need oil, only grease. What is the oil for and if I need it then how much do I put in? I’ve done rockshox services before and they seem similar to this but I can’t figure this out. Thanks!
