There are no "stupid" questions on great sites like CRF's Only!
Now your question - not many people have probably done what it appears you have by flipping the forks & listening to them.
You did not state what bike the forks are for. If they are the tube up and lower down type -for example the CRF230 style I would guess it to be normal to hear the oil transferring from bottom to top when flipped.
The CRF250-450 style fork I dought you could hear any oil transfer. But that said I have never flipped mine over and listened.
So what bike are they for ?
I'm sure there are several fork guy's that can answer your question easily.
