Help needed (mechanical advice)

Ok i have a question and was thinking that this is probably the best place to get an answer about a GS500.  Well, i just changed my oil and now i have a oil leak (see pic).  Not sure if it is a bad gasket or if i over filled it, because it is still showing full, i haven't added any oil and its been leaking for at least 3 weeks.So what do you guys and gals think?  if the pic doesn't work here is the link. http://viewmorepics.myspace.com/index.cfm?fuseaction=viewImage&friendID=401225759&albumID=684632&imageID=8815914

that's from your chain, usually.

when you oil your chain it slings off, and looks like the gasket is bad.

That might be but i have had the bike for about a year and a half and i have never noticed it before.
