Oil Leak

[Fazerider]

What about all the hosing around that area, they are covered in oil is there any chance it could be leaking from one of them?

None of them should be carrying oil. Fuel, air and coolant but no oil.
The crankcase breather will have a light oil mist present, but if there's a lot of blow-by past a piston or the engine's been overfilled it can be a bit more than that.
(OK, there is a drain for the airbox which can dribble oil blown into the box by the breather, but it's hard to see how that could get on the carbs as it's routed to drip on the ground behind the engine.)
