Blown fork seal

Hey there. Anyone else blown fork seals? I got 4600km on my bike came back to my bike after work and noticed oil all over the front wheel.

I have had dirt and dust in seals on previous bikes but I find those leak slowly. This seemed to be 1/4 cup, with most of it coming out while the bike was parked as it was pooled up on the rim.

thanks
16 586 kms on my 22 Norden and both fork seals started leaking. HQ. Says no warranty I say its bullshit…
 
They will build up pressure with temperature or altitude changes. Leaks are the result of dried dirt getting shoved up in the seal. Even a minute amount could manifest a leak, especially if there is an air pressure build up . I can modify the fork caps to add bleed screws. Its a relatively simple machining operation.

I believe I have some of the 43mm seals in stock if anyone needs them.
Do you sell the modified caps?
 
So indeed I did have a buildup of crud similar but not as bad as your Versys pic there.
I removed the dust seal and cleaned out the oil seal and had a blast of pressurized oil shoot out all over. I cleaned the crud off the chrome and put everything back and after 3 days of riding there is no more leakage. Hoping it’s going to stay like that as the local dealer has no idea when a set of seals would arrive. Im starting to really despise HQ for their lack of the simplest maintenance parts for their bikes.
In the meantime, I would like to add a set of pressure relief valves to my caps. I am in BC Canada so sending off my caps is not such a great idea.
Do you have any advice on what or where to get the pressure relief valves?
thanks for any ideas…
