I drained and then pumped the foul smelling (but clean looking) oil out of my forks, flushed then with solvent, blew then out with compressed air, and then refilled them with 10w fork oil. Man, 5.4oz is not that much at all.
I also made a big mess on my garage floor with foul smelling fork oil and solvent. Luckily, I had it cleaned up before the wife got home, and the solvent smell is mostly masking the foul fork oil smell.
