Fuel in oil (suzuki 90A)

[Daz2484]

Hi i serviced a suzuki 90 2010, the oil was full up to the top of the dip stick, Upon draining oil was very thin and seemed to have fuel in it.
Removed plugs and carried out compression test, Bottom cylinder was high and oil was coming out of bottom cylinder.
Diagnostics showed only 28 hours done 75% of the time in tick over.
I am going to start investigating more monday was just wondering if anyone had come across this before, everyone i have spoke to has not heard of this in the new 4 strokes.
Am going to check the injectors first, any theorys are welcome

Yes, sometimes fuel leaks into the crankcase from the fuel pump.
