After reading the post/pictures that Smitty posted on the bushings/seals in his fork tube I have a question: Regarless of how or when you change the fork oil, why does is appear so dirty? If the replacable parts in Smitty's post aren't showing a tremendous amout of wear, what is wearing to cause so much sediment in the oil? Or is is a case similar to "blood in the water"...where a little bit looks like a lot? Just seems to me from looking at my chain case oil, motor oil and transmission oil, and the shock oil and letting it settle and using a strong magnet, there was a significant amount of metal in the shock oil compared to all the others. I am not saying this is good, bad or indifferent, I am just wondering where it is coming from since I am not sure how the shocks work from a technical/hands-on standpoint. Again, this is my first HD so I am learning as I go..
