The manual says 190cc. (3/8 US pint).
However, a little bit over helps if the forks 'clunk' at the top of the rebound. This is because, if too low, the two small bleed holes at end of the stanchion move into air space and don't do there job as a 'final damping'. (Well, that's my take on it. Other opinions would be welcome).
Hope this helps.
