Can't tell a lot from your picture but are you talking about your clutch cable or a hose somewhere?
Yea, I sorta thought he meant clutch cable, since you can see that it is leaking from there a bit. But, he said nothing is actually "leaking", and it is a "hose" that is "sweating"?? So I am confused.....or someone else is.
But to me, it just looks as if the clutch cable is leaking a tiny bit.
I can't view the pics, but if it's leaking from the clutch cable, and it's still under warranty, take it back to the stealer. They put one on my bike while it was still under warranty.
Mine did the same , there was a little breaking on the plastic cover so i first tried with silicone, than with heat pistole, at last I changed the cable and it fixed the problem.
