How much fork oil?

[wellsplattered]

Hey,

Just stripped down the forks, rebuilt them and now they are ready for some oil. How much should I put in??

Any help appreciated
Thanks

Workshop manual says this:
SPECIFIED LEVEL: 182 mm (7.17 in) See below!
CAPACITY: 405 cm2 (13.7 US oz., 14.2 imp oz.)

Haynes says:
25 Slowly pour in the specified quantity and grade of fork oil and pump the fork to distribute the oil evenly. The oil
level should also be measured and adjustment made by adding or subtracting oil.
Fully compress the fork tube into the slider and measure the fork oil level from the top of the tube (see illustration).
Add or subtract fork oil until the oil is at the level specified in the Specifications Section of this Chapter.

This is at the beginning of the chapter:

*Oil level is measured from the top of the tube with the fork spring removed and the leg fully compressed.

So only the 89 model has a 182mm level.
Also, try using different oil as standard, I used 10w, instead of the 5w. Some even use 15w.
