06 wr450 fork seal maintenance
Posted November 23, 2009 - 10:15 AM
After 9 riding days, I went to an MX track, and the left leg blew its seal - oil everywhere.
I took the forks to Aftershocks here in the bay area, and Phil serviced, revalved, and resprung the forks for my weight [210 lb.s].
4 riding days after that, with me still wiping down the sliders and seals after every wash and before every ride, the seals on both fork legs began leaking again. Aftershocks replaced the seals and charged me for the parts, but not the labor.
Now, 5 riding days after the second set of seals - I'm still wiping and cleaning the sliders and seals like a fork cleaning fiend - they weep when stored; just a few drops trickling down from the seals. When I'm out riding, they don't leak at all.
I've gone through my owner's service manual and it doesn't explain how to clean the seals before or after normal operation.
 Am I damaging the forks by riding when they weep during storage?
 Will simply installing the sealsavers I just bought fix this?
 What is the best way to address this?
Thanks any help you can offer.

I found a reference to 'cleaning seals with a business card' on this forum [It referenced 'fork seal maintenance suggested by Neal'
but the link to Neal's wisdom didn't take me anywhere. It seems searches for 'how to clean seals' only takes you to one of several different marine mammal preservation sites.
I am more than happy to accept any help/direction/chastising/criticism that will get me on my way to better riding, less fork oil leaking.
Thanks - clearly I am still a newbie.

Seals should last quite some time unless in REALLY bad conditions. SOmething is tearing them up prematurely.

One TT dude said Neal knew the way, but I can't frickin' find that way!

Did the guys at Aftershocks not have anything to say about the seals they pulled out? are they using OEM seals?
The "business card method" is that you use a business card, piece of 35mm film negative or a feeler gauge and just run it around under the edge of the fork seal, just in the section underneath the spring - 5-10mm in, nothing fancy, you should get a little bit of gunk off of the card etc, this is normally used by us rough bastards that ride in dunes and don't look after our bikes, I do have a set of sealsavers on order after my current re-build is finished though

So far the sliders look immaculate. I have a friend with an 06 and another buddy has an 08; they've both done their fork seals after 8-12 riding days, but theirs seem to be holding.
I'll stay on top of it.
