fork seal blown.

NO jokes about sea mammals and fellatio please.
The wife just noticed a small oil slick under my bike and I find fresh
oil on my right fork.
I see that Fred sells "MSRHP Fork Seal & Wiper Kit" for $29.95.
We have not been riding much these days, but I do want to keep the bike
in happy/working order.
Any advice on the "best" thing to do in this case?

Doug - Pass on the enigmatic tales of superglue and radiatore sealant
and get'er fixed properly.
I installed Fred's MSR seals and can recommend them. Although I'm
not sure how much better one seal and wiper kit is over another.
Longevity might be the only difference but who knows. I've heard
some folks say the OEMs are as good as it gets; a cheaper set Fred
sells carries a lifetime warranty. Again, before I'd sell you any of
them, I'd like to see the proof myself. Just make sure when you're
done you rub a touch of 'dry' lube on the forks before entombing them
under das boots. This will reduce stiction right out of the gate. I
use Pedros Extra Dry lube from a bicycle store but a spot of fork oil
is fine, too. And don't forget to pickup fork oil to complete the
job!
Of course the KLR650 braintrust is always at your disposal. This is
a good website to get you started...

Doug - one added reminder, I used one of the old seals and a piece of
wood to drive in carefully the new seals. It worked fine for me
instead of making or buying a special seal driver. No need.

Here's a couple of sites for seal r & r. I used the air method a few
months ago on both my bike and my wifes. It works well. I left my oil
in when I pressured up the forks but covered them with a cloth, go
slow with the air as you pressure up. Your fork will extend full.It
worked find. I did find it took some finesse to get the new seals in
far enough to get the keeper spring to seat. I used a wide flat
screwdriver and took my time.

Hello Doug,
I am most likely the most recent 'fork-seal' replacement on this
list...and I only had one thought when I saw my seals were blown at
the midpoint during the GDR last month....
OEM seals. period. (Not that being most recent, makes me most
smartest.) shrug. Just the most recent....
In my five years of reading list wisdom, OEM is the one that has
disappointed the least--none that I recall--and many that
installed 'trick' fork seals. The failed seals I replaced, under the
watchful eye and tutelage of Jeff Saline--were aftermarket seals--and
they did not last 5,000 smiles--installed by PO. I know the bike was
not jumped or flown--thus abusing the seals during that 5,000 smiles.
Were they properly installed? I trust that they were, based on the
PO general experience with moto's over their lifespan.
I also could not believe how filthy the oil we drained out was in
~10,000 smiles. It hardly qualified as oil, more like liquid gunk.
The aftermarket seals were only ~66% of the thickness/height of the
OEM seals--so much so, we initially thought the installed seal was
only a wiper!
Pay attention to the orientation of the 'parts' in the bottom of the
fork tube.
ie.
Clymer Manual, pg 259
Ill #30
part # 19; guide bushing
The parts diagram is not helpful, and is not very clear. We watched
the orientation carefully during disassembly--only to discover, one
was cup side up, one was cup side down.
If you full disassemble the forks, be sure to thoroughly clean the
inside of bottom fork leg. I finally pushed high pressure water into
it and blew out the crap. I had worked for an hour attempting
to 'cleanse' the residue that I finally removed in
fork seal blown.

Revmaaatin - Where is the love for the aftermarket? I'm still
attempting to return to nature my new MSR seals. So far nearly 10k
smiles and all systems go.
As for pressure washing the fork internals. I can't recommend this
to viewers. You'll never displace all the water especially vapor.
Far better to flush with fork oil for a tiny incremental cost. Once
you drain them and pump some fresh thru, it's clean enough.
For the record, the dive of death (a big granite drop in an
undisclosed location in the Rockies) that destroyed one of my front
OEM seals did nothing to my new seals. If I recall, you've had a
fork brace on your KLR which I can almost guarantee accelerated the
demise of your oil and seals. We're not talking grassy knolls
conspiracy theories here. I just pointed the following to a buddy
who has a brace on his. I'd never used or seen one before but my
uncanny attention to detail of his predicts bad juju.
If you look at the force brace installed, you had to force-up the
bottom of das boots to get the brace to fit. In doing this you
reposition the (holes) drain ports from the fork receiver up onto the
tubes themselves. (eh hum) Crap is now going directly in and onto
the tubes and compromising your seals and oil. For extremers and off-
roaders, unprotected fork tubes is bad juju and explains the fork
julius you were surprised to find. This is how important these boots
are to prevent contamination and why the manufacturer puts hose
clamps at the top of das boots.
Reinstall some MSRs and re-seal the deal. Provided the integrity of
the das boots isn't compromised, you're very unlikely to see this
happen again.

ps - Did you get my response to your gumbo mud destination post? I
didn't forget you 'in the Valley.' Actually I thought I had a clever
response to you. Anyhoooo, that remaining 1% mostly represents those
that let it sit in the garage.

You may well need to replace the seals, but on the theory that the "best" thing to do is the
simplest and cheapest, try using a thin piece of plastic (the electronic access cards they use
in motels are about right) under the seal, to wipe out any bit of grit that may be trapped and
causing your leak. It's easy, costs you nothing, and if unsuccessful leaves you no worse off
than when you started.

Doug,
My money would go to new OEM seals. I think they were about $27 at the
dealer when I picked them up for Martin a few weeks ago.
Someone suggested you try cleaning under the wiper. A local Moto-X shop
sells a piece of plastic just for this operation. I've also heard you
can use a piece of film from a 35mm camera. Maybe get a scrap at the
local photo developing shop.
Best,

Brian,
The forks were totally apart when Martin used the pressure washer to
clean the inside of the sliders. It worked well. No worries about
trapped vapor. I think the inside was also dried with compressed air and
a clean rag on a stick.
For the cost of OEM fork seals I'll stay with them. Mine are still good
at 27,000 plus smiles.
I think the fork brace may have contributed to the leaks but nobody will
ever know for sure. Martin didn't reinstall it when finished with the
forks. He was hoping to decide after a bit of riding if he'd put it back
on or not. I'm betting he doesn't.
Best,
Jeff Saline

Interesting use of playing cards...and a whole new reason to viva Las
