Clean the bike off and give it a good inspection so you can see where it is coming from . Could be fork seals leaking really bad , water pump seal or an exhaust leak , or the right clutch cover leaking .

ya i think that my bike has been running really rich and that oil is blowing from a seal in the exhaust pipe. thanks for the advise!
