as above really I looked on tftuned and they have many different weights.
How heavy are you?
Depends on which bit you're oiling. The norm for most rock shox forks is 5wt oil in the motion control damper (upper right leg) and 15wt oil in each stanchion (lower legs).
All the info can be found on sram website.
All I'm doing is putting some travel reduce spacers in there. I don't know my exact weight.
If you are putting spacers in you don't need to touch the damper.
Therefore, 15ml of 15wt oil in each lower leg (although I use 5w30 synthetic engine oil since it's designed for lubricating sliding things, unlike fork oil (which is for dampers)).
Go here: http://www.sram.com/en/service/rockshox/tech_manuals.php
Scroll down a bit, passed all those boxxer manuals and you'll see some tech manuals download one and have a read. It says in there 15wt oil for the lower legs and 5wt oil for the damper system
thanks people
I do the same as glenh, for the same reasons. 8)
