If you mean a piston ring compressor, I can't see how that would help. Just looking at the shock I think that the chromed cover sits under the aluminum casting. You would need to take the spring pressure off the casting in order to unscrew it from the centre rod and you would do this by pulling down ...

The story I have heard is that they attached to the air filters with the intent of drawing oil into the valve guides. Original air filters have the connectors but newer ones don't so it seems that Honda thought them unnecessary. I have some little rubber caps over mine but there seems to be no harm ...
