Since the forks "went south" all at once, could it be possible that you have is some new wear on the parts? Certainly you can't get all the old oil out without a teardown, but if the other oil didn't lubricate correctly maybe you have new damage. What is worn? The bushings?
...and the story continues...
I guess anything is possible but I'd be extremely skeptical that the new oil didn't lubricate correctly.
For what is worn, I gotta break out the book and try to figure out the proper names for all these widgets...
Let's see, the dust seals were allowing water in, and the stopper rings were rusted. The springs were way in tolerance...so no problem there. The rest of the parts I'll give more detail when I have a chance to compare them to their new counterparts where I think differences will be more glaring than in my darkish garage. I suspect the damper rod and piston ring, fork tube bushings and oil seal will need to be replaced but hard go gauge just how bad they are without a gauge.
Hey Greg, how 'bout I just ship the forks to you, you can tear 'em down and take pictures for the site, then reassemble them and ship 'em back?
I'll give an update when I can get the new parts and tear 'em back down and compare stuff...one thing I didn't check is the tube. The Cymers says if the tubes are scarred you must replace them. Makes sense, but I might should've checked that!
