i need something like
Stendec Crystal Fork Fluid
SRAM Red Rum
Rock Oil SVI Suspension Fluid
or
Stendec Crystal Rear Shock Fluid
or anything else????
Also best way of measriung the amount???
Your best bet is to head down your local MotoCross shop, and get yourself a litre of each of 5wt and 15wt fully synthetic racing fork oil (MUST be fully synthetic, not the cheaper stuff) from the likes of Silkolene, Putoline or Rock Oil. It's usually under £10 a litre, and MUCH cheaper than buying "MTB specific" stuff (which is only the same in smaller bottles).
The 5wt is for the damper, the 15wt is for lubrication (ie. in place of the gunna flow/red rum lube).
In terms of measuring, get yourself a measuring cylinder from a cookware shop, or even better, get a 50cc syringe (best place to get them is your local Cartridge World, just ask for one, they use them for filling cartridges, they'll sell you one for under a couple of quid).
This should see you right…
