Fuel getting into oil

Hi all new member having difficulty stopping petrol getting into the oil? People told me my zr7s has a vaccum operated switch and sometimes the rubber perishes, so got a new kit replaced it and still seeping through. I am now going spare as this is the third time I've changed the oil and filter without the cost of the fuel. Don't know what to do next so any input would be much appreciated. Cheers Kevin.:-|

The carbs needle and seat also have to be leaking for this to happen. So there are two failures or that is what i suspect. I do not know exactly how your bike is configured though. What year is the bike?
