Sludge in Air filter..900rr

I noticed yesterday when checking the air filter, that there was some whiteish foamy sludge inside the top of plastic airbox, in the front right corner. I didnt appear to have come thru the filter as the filter was clean, as were the carbs. This was not on the engine side of the filter, but on the top side.
It has been VERY cold of late, and the bike is stored outside under a cover only.
However, i cleaned it out with a rag, put it all back together and went for a ride for about 5 minutes.
When i got home, i checked again and there was some more of the same deposit there.

Is this normal, could it be filter oil mixing with cold air, or could i have a more major problem to worry about????

Its on a 95 900rr.

I am taking the bike to get some other work done to it later this week, as it detonates badly, and is running low on power, which everyone has put down to jetting, but now i am wondering if these could be somehow related???

Re: Sludge in Air filter..900rr

White sludge would sound like water/oil mixing. it could be due to very short trips, not getting the engine hot enough to dissipate the condesation that inevitably forms, or, could be somthing worse...
