If they are original, 230cc per leg and I used 30w in my ones. 30w is a bit hard to get, you could try a hydraulic oil 68 which is around 25w.

    30 wt oil . No way. Unless you weigh 120kg +.

     Use only 15wt .  Castol or Shell or any other good Fork oil.

     We use Ake Jonnson Fork Springs. Worth the Money.  For Rider weight of 85kg.

       230cc is correct.  But you can add 10cc to 20cc for a heavyer rider or better make a alloy spacer and
preload the springs 5-10mm.
