Engine & Transmission
Oil up through crankcase breather

Hi all, Apologies if this has been asked loads. Wanted to check my spark plugs because I have a slight flat spot at 4-8k rpm so thought fueling. Took the airbox off and I found oil ontop of my carbs where the airbox bolts onto. Took the plugs out and they all have oil/oil residue on with Cyl 2 being worst. Did a compression test and the results being Cyl 1 150 psi Cyl 2 145 psi Cyl 3 142.5 psi Cyl 4 142.5 psi I am going to do a leak down test as soon as I get a tester/can borrow one from a mate as well as use an endoscope when i can borrow one from a mate. Does any advice on what it could be or what to look for. The engine only has 3.5k miles from new and Ive only had it for the last 500 of those miles. Admittedly I do ride it hard but I always let it get to temp before I do. Any advice would be greatly appreciated. TIA.
