It appears from the 1st photo that it's likely to be the transmission drain plug.
It will make troubleshooting easier if you clean the area, then check drain plugs.
If it persists, then check vents, etc.
BTW- In general, stop leak products are bad ju-ju.

 

Negative on the enfgine goo. If you have to open the enging after using any type of stop leak you will be cleaning for months.
Plus, that crap will plu up everything. Unless you own somethingolder than my 1982 FXRS, stick with factory advice.

 

No, do not use that stuff on the bike. If you or one of your buddies have basic wrenching skill just fix the leaks.

 

Agreed. Stop leak type products are generally to be avoided. Bad juju!
