That's what I was asking myself this morning when I went to change it out on my 02 300 MXC open chamber forks. Opened the left fork and found the spring had rust on it and there was water drops on the inside of the cap, awww crap . What little bit of oil still in the fork was a nasty looking grey/brown and had the viscosity of water. Full dis-assembly (no other issues found) , clean, flush and refilled with fresh oil. Right fork had the proper amount of oil, but it was grey/silver metallic . Can't catch a break anywhere. Same proceedure on this fork as I did on the left, no other issues found, refilled to the proper height with fresh oil. A short ride around the backyard / alley dodging the easter egg hunters indicated MUCH better performance, will give it a good test next weekend.
