Hi Mark,
If it is leaking from the little pipe (4-6 mm dia) then this is fuel, I would think. I had a 98 Funduro and in the 80,000km I did on it I don't recall ever dumping oil, but it did dump a little fuel out of one of the two pipes, usually when I overfilled it if engine was hot - trying to squeeze max kms on adventures 😆 Does it only happen when he has filled up?
The air box has a drain pipe but this is quite big 8mm + dia but oil can come out from this as the engine breather vents to the air box. More so when Kms get high, how many has he got on it?
The fumes/oil mist from the engine can build up over a while and cause some oil to drip out. Tell him to take out the air filter and have a good look inside the air box clean out any excess oil. Would have to check for heavy breathing, The bike!!!!!!
All the best
