fork oil capacity and weight

Wondering if anyone out there would know the correct quantity of fork oil and the weight for a '89 NSR250 MC 18?

Thought I would change it but not sure what it has-probably 10-15 weight.

cheers

These are oil levels, which are measured from the top of the fork leg at full compression, with no spring. The Honda service manual recommends 10W oil.

Cheers-thanks for that. Seems to have slightly un-even damping so wanted to check that out-may have leaked some out although no visible signs of leaking so thought I'd start by draining & refilling with correct weight and quantity & go from there.
thanks again-
