I'vre got one litre of the correct grade of oil, is that enough to do the job. ALL the parts including instructions are 25 miles away in my daughters garage, so I can't, err obviously read them.

I think one liter is enough to do both forks.
If I recall correctly, I used somewhere around 450ml per leg when I did mine.  :scratch_one-s_head:

This is how much I had left in each 16oz bottle after filling each leg.

Yes, you will need just under one liter to fill both forks. But make sure you have the correct oil. It is 5W, any heavier and the RPM valves will not perform as designed.
The glass is not half full, it was engineered with a 2X safety factor.

Yes, it is more than enough as you will have a little left over.

I just saw the photo that Monkey posted, that is the correct brand & weight of oil, but not the recommended oil. Monkey has shown a picture of the "Expert" version of the oil. That oil will allow the valves to function properly, but since it is a synthetic blend the life span is not as long.

The "Factory Line" full synthetic is the recommended oil: Motul Factory Team Line 5wt Fork Oil
