Brand new EXC - Fork seals leaking after 2hours

Hi,

is there something wrong with the new (green) fork seals on 2013/14 bikes?
The 500EXC of a friend started leaking after just 2,000km, we blamed it on sand and salt water and repaired it. Now my brand new 2014 300EXC started leaking after just 2/3 hours of riding, only seen slight mud, no deep water or salt and sand.

On my previous bikes and those of the buddies, various Husabergs, EXCs of all kind the seals lasted 100-200 hours in deep water crossings, tons of mud and all other type of abuse.
Just bad luck or some quality problems recently?

greetings

Idk, sounds like bad luck or bad batch of seals. My '09 450 have yet to leak a drop.

Seals need some miles on them to seat completely. If you took straight to the dirt, there's probably just dirt in the seals preventing them from sealing effectively against the inner tube. Try SealMate. You can also use a bit of very thin film or a thin feeler gauge to try to clean the dirt out from underneath the seals. It's cheap and it's definitely worth a shot. If dirt in the seals becomes a repeated issue in the future, you may want to try Shock Sox or similar.

This ^^^

Very rarely do fork seals "just go bad"
There is just some dirt in there, and most likely a seal saver will do the trick in about 5 minutes.

If you can get some old 35mm film or thin tape to clean the fork legs it's usually a piece of grit that's worked it's way between the fork leg and the seal.

I doubt they are bad.

I used the 35mm film trick in the 90ies, since I don't have any of that stuff any more I now use the Risk Racing Fork Seal Doctor.



They cost around $25 online and work great, IMO much better than film, business cards, MP Seal Mate etc.

Bet that solves your problem

Thanks for the tips, i'll send the forks to the dealer to solve the problem. Luckily he's just around the corner...
