No worries ChriSTian_64. Most any information is new to me, so all is helpfull, even the jack-thread.@Mckeith, sorry, don't want to hijack your thread about hard front suspension.
I checked in the honda service manual, and they say that another possible cause (beside improper oil weight or level) might be a clogged anti-dive mechanism.
So, instead than just changing the oil, it might worth it to open that mechanism, at the base of one fork, and make sure it is not clogged with jellyfied old oil.
