I've detected a leaking fork seal. I say leaking but it's really only a smear of oil that's showing above the dust cap/seal. What's more it seems to be leaking, or rather weeping, only intermittently. Yesterday after a ride I found a trace of leaking fluid. I carefully cleaned up the fork before I rode out today but when I got back home and checked the seal no leak was apparent. The problem is, and this is where a bit of advice would be much appreciated, I'm off to the Black Forest next week, fully loaded, two up. Is this an issue that can be left until I get back or does it need sorting pronto?
