Get on the ground and see if the oil is coming from the oil drain plug before you tear the plastics off.
What he said.
Does it leak while parked, or only while the engine is running? Wipe off all the oil that has already leaked out, then keep an eye on it for a little while to see where it's coming from. If you have to run the engine to make it leak, be sure it's at a safe oil level and let her rip. Lie on the ground if you have to and wait for results.
if the bike is new to you...which it is,this is a great starting point. Oil pan drain plugs are easily stripped by those who are shall we say..."less mechanically inclined."
did the previous owner have a decent shop with good tools? Or did he have a bent screwdriver and a pair of rusty vicegrips?
