fork oil

Quick question so I can finish the forks on my 1982 Honda CB750C Custom. Just got progressive springs from the VintageCB750 website, and cut spacers to length to match stock. Also had them powdercoated black. I have a Clymer's book that only states 155cc of fork oil is needed, no indication...

Hi. According to the papers of my bike I have a cb750F K2 from 1975. Thats a model I can't find anywhere. I can only find just F or just K2. And them both two models needs a different amount of fork oil. So how do I know the right amount. I believe it's a F since the K2 where made 1972. Anyone...
