Possible antifreeze leak?

[Fazerjon]

Well that's strange, I've cleaned off the area, checked the dreaded 'weep hole' and been out for nearly an hour on the bike. No sign of any leaks! I decided to change the coolant as well, so did that and went for another ride. Levels all good, no leaks. Still curious though. The nearest hose to where the antifreeze was, is the one that goes in to the sprocket cover. I've checked and squeezed it but nothing. Strange.
Cheers anyway.
