What's the bike's mileage? Also, are the breather hoses connected to the airfilter box, especially the crankcase breather hose? Perhaps you have excessive oil spewing from the crankcase and collecting in the box? Otherwise, it has to be leaking past the rings from the engine side and getting in the carbs. On my bike, the crankcase breather hose got blocked and actually backed oil up through the fuel pump weep hole, it was spewing out. Those vapour have to vent somewhere.
