You are wise to change the fork oil quickly; you will not be sorry you did so.

I think it will difficult to put spacers at the top of the fork, since tightening and loosening the nut on the damping rod is the hardest part of the job, especially if you don't have a very thin, 14mm wrench. You might be able to put a spacer at the bottom of the spring, but you might not, depending on the ability of the cartridge to support the spacer. When you have the forks apart, please do take a good look and evaluate this option for us.
