• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Best replacement seals for factory Marz?

Ive now blown 2 seals on the 09 WR300 front zokes.

Is there a better option available than the factory seals?
I have also fitted air bleeders but hasnt seemed to help.

I have the same problem with my 09 forks. 2 rides on the last set. Fork tubes are good, no nicks or scratches.
 
This is a common problem. There are aftermarket seals out there which are suppose to be better but Ive lost the site and brand details.
 
I got 2 rides on some synergy seals before one blew, I will try SKF next. I also read somewhere?? that if you replace some bush? it fixes the issue permanently. Must be too much play from the factory.
 
Have you tried cleaning them? Many fork seal leaks are caused by dirt getting stuck in the seal. I pull the dust wiper down and work an old piece of 35mm film under the seal and slide it all the way around. It's worked for me at least half a dozen times on various bikes. I've managed to go over 120 hrs on the original seals by cleaning a few times. I got SKF seals to put in next time I change the fork oil.
 
Had this problem from day one on my used bike.... However, I found a nick in my stanchions... I ordered a brand new set of stanchions, new bushings, and a brand new set of SKF wipers and seals... This lasted about 15 hours 4-5 rides before they were leaking again. Pulled the wiper down, stuck film in to clean, and it's good again... IMO, these forks are just prone to it.. BTW, I have 50mm CC Zokes... I also have bleeders, and release pressure all the time, including when I tie down in truck, and un-load it.

I also learned a trick from Bills Motocycles Plus. Take the spring off the wiper (it threads into itself like a screw), and cut a few (4-5) coils off the female side, and re-assyemble. This tightens up the seal on the wiper a bit.
 
I had 105 hrs on my SKF seals before I replaced them.I waited 3 times too long to service my forks.I always wipe the forks clean before a ride,bleed air before and after and use seal savers.My suspension guy was amazed they weren't leaking.Even with my precautions there was still dirt behind the seal but no leaking.My oil was pretty much like dirty water but was all still there.
 
Talked to my suspension guru Bill at ccycle...definitely found dirt all the way in on the bushings. It seems when the fork bottoms, the dust wiper hits the brake mount bracket and creates a side ways force on the lower tube, possibly allowing air, and dirt inside and wearing out the bushing. A little grinding to make room for the dust wiper when bottomed out, new seals, a tighter spring on the dust wipers and hopefully we can get this sorted.
 
unscrew it. Find the junction in it. It screws onto itself. Cut 3-5 coils off the female side. I always pre-tension it counterclockwise so when I screw it back together, it is sitting in its natural state, and not wanting to unwind itself.
 
Ah, good tip, if there is extra stress on the join might put some lock tight on it. Just checked it, pretty small item.
 
Race Tech does not have the bushings for these forks....said they no longer stock them. Where can I get them?
 
I bought some off ebay a while ago. out of 4, only two of them were correct, luckily the guy took returns... Then I called Bill's Motorcycles Plus in Salem, Or, and got the correct two I needed.

I'm sure bills can help you. Give them a ring.
 
Since I needed the bike for the weekend, we reused the bushings for now. New seals, tighter spring on the seal and wipers, and went to 10wt oil...thinking it might not leak as easily. Not sure how it will affect the handling...felt a little harsh today, but that might just be the cold weather.
