crf450 airbox question

I did a supermoto trackday using my CRF450R with some barrowed 17's. It was a blast. I am hooked.

By the end of the day I had oil dripping out the bottom of my airbox. I was getting alot of blow back from the engine or crankcase breather hose. Is this normal when you supermoto a CRF450?? This is my second trackday and it did not happen the first time??


Help! I cant figure it out.
