Oil leaks can come from LOTS of places, and simply looking at areas where oil has collected will not usually provide an explanation of their source.
Something I noticed that I would devote time and attention to is the oil pan seal. It appears the PO used RTV sealant (the light blue goo around the oil pan) and you want to drop the pan, and remove that NOW. It is infamous for chipping off and finding its way into the sump and oil passages. You should not need sealant outside of the stock oil seals. If you do, you've over-tightened the pan. Stock oil seals work perfectly. Aftermarket are hit and miss.
Take some photos of the engine at the front, side, under the shifter side cover, etc. skip the videos. Places that could be contributing to your oil leak are the oil under the shifter side cover, a head gasket, a leaky valve cover, etc. Turbulence from the wind while riding will drive the oil a long way and confuse you as to its source.
