fork oil weight recommendation

[bjohn07]

so my head bearings have play. figured id freshen up the forks while im at it.  manual recommends kayaba 01 never heard of it.  or se sae 5w20.    prob because this manual if from 92.  anyway  whats a good weight for this bike.  im not gonna race it.  mainly trail riding, take it to a local track probably twice a year just to mess around.  im 180 pounds.      i was thinking a 10wt?   and how much is a good level to start with.  book is saying 506-516ml?

5 wt is what I use, I'm 200 PLUS LBS, if stock springs you could mix 10 and 5 together. 10 on its own will be much harsher through the stroke.
