Spewing Dragon

I ran in to a bit of a problem, when I took the bike for its first quick run I had oil spewing out of the dragons exhausts, I actually drained out nearly 500ml from the mufflers. It took me a bit of thinking bt I narroed it down to the auto lube pump having corrosion on the cable, so a quick spray of mechanic man in a can (aka WD40) and everything was flowing freely except the oil, this was now limted and didnt flow freely out the exhaust...
