At 30k miles your bushings will be showing some wear... so somewhere between 30-40k, just do a full rebuild (bushings, seals, oil).
Ray, I read an article that advised that one can extend bushing life by rotating the upper fork cylinder 1/4 turn within the triple clamps to change where the bushing wear takes place. Any thoughts or experience?
While I have not given that a lot of thought, it does have merit..... bushing wear is on the forward and rearward side of the lower bushing, so turning it 90 degrees would indeed put you in fresher teflon territory. I'll buy that, just never thought of doing it.
We should also mention by that 30k, the lower has been sliding up and down continuously in the lower aluminum tube. This creates aluminum fines that are "in suspension" (there's a pun there) in the oil, until there's too much of it and some sinks to the bottom..... contaminating the damping sets and if really bad, blocking the compression damping port.... so ya really need to be taking them apart and giving them a good flush, IF you haven't been changing the fork oil at more frequent intervals.... which you can do any time. So... new recommendation, change oil every 10 k and rotate the fork tubes 90 degrees.... would take you to over 50k before needing bushings. Kool.
I'll also mention the middle bushings on Gen2/3 do nothing much as far as a few of us can tell... never worn. I think that's due to the bushing expanding into its groove when it seats. The middle ones are however very likely destroyed by removal when the lower bushing slide-hammers into it.
As well, the upper bushings are never worn, may not even be damaged by the slide-hammer removal method. Excellent chance you can re-use them. I have a collection if you need a couple.
