1 '85 K100RS fork questions Thu Aug 18, 2016 5:47 pm

My K100RS has what I would consider excessive dive when I brake. I bought some Wurth fork springs, thinking that at 45 K miles, the OEM fork springs may be a little tired. (BTW, the Wurth springs are not labeled for their weight, so I've no idea if they are a different spec. than the OEM springs.) If I change the springs, I'll also change the fork oil. My Haynes K100 manual seems to have vanished among the clutter of the garage; I looked at the riders manual for the bike, but wasn't able to find the mount of oil the forks should contain. Can someone tell me how much oil the forks should hold?
In a related issue, my understanding is that a bit less oil would make the fork action more progressive and a bit softer; more oil should make them less progressive and a little firmer. Correct?
Should I fill them with 10W oil?
TIA
