Source of oil leak?

[kongjie]

Sorry for the delay in updating the repair.

The shop had the bike over the holidays because the part was coming in by UPS and ended up getting caught up in all those delays.

I believe the part number is 09280-10016 and I'm pretty sure it's the item circled in light orange in the image.

I'll admit I was skeptical when I picked up the bike. But now almost a month later, there is no leaking, and what's more the strong smell of burning oil that I could smell when I turned off the engine has more or less gone away.
