Oil Leak from Cylinder Head???

I noticed a little oil leaking from my left cylinder head (when sitting on the bike) yesterday and could use some advice/help. Here is the back story....

2013 8vSE with just a bit over 3,000 miles (4828km) It had 400 miles on it when I bought it from Jim up here at Rose Farm Classics in Illinois back in March. No issues with the bike thus far and love it ever day.

Here's the deal....

Riding home from work last Friday in the usual stop n' go rush hour traffic; the ambient temperature was about 93F (33.8C) and the bike was running as normal. At one of the stops, I smell something like burnt oil but at the time didn't know if it was coming from my bike or the old junker car that was in front of me. I get home and when the bike has cooled down I go out and to inspect and notice that there is a drip or two of oil on the lower cylinder cooling fins (not sure what the official name of those things are). I took off the left side fairing and it looks like the oil was maybe coming from the oil line that feeds into the cylinder head? I did try to tighten the oil like bolt and it moved maybe a millimeter...not sure if that would be enough to make a difference. I took some photos and hope someone has some advice. The oil level is still okay so I don't think it is a major leak but I am scared to ride it without really knowing what's going on. Would/could something like this happen if it was getting too hot or was it just that bolt that got a little loose that may have caused the problem? https://drive.google.com/open?id=0B-6-KyqSqKMucWIxcnRCdDRFY2s

Try to look at the oil pressure switch. It is in the same area and is prone to leaking. Most oil leaks as you describe seem to originate there. Mine just did it also. The oil runs in the V and then out the left front and looks like your photos. Mine was on a hot day also but I was on a trip and by the time I noticed it I had oil there and down on the sump. Just a few drops made it to the ground and I continued riding it the next day and about 500 miles. Oil level did not move enough to notice.
 
Also the phase sensor should be checked. I think you found it with the oil supply line. After cleaning the area ride the bike. If it continues, check the mating surfaces and replace the crush washers if it is still from the oil supply line.
 
Thanks for the feedback. I'm gonna try and clean up in there and take a spin to see if I can isolate exactly where it's coming from. I appreciate the feedback.
 
No idea how to remove a post but I accidentally posted here when it was supposed to be in the thread I started on my oil leak. Sorry for the interruption. :angel:

No worries "abbienormal". For what it's worth, I snugged up that oil line bolt and crush washer and after a 10 mile ride, I didn't see any leaking so I hope it just needed a little break-in torque down. We shall see once I'm in hot stop n' go traffic.
 
Hi.
Don't Forget to check the valve cover gasket....I had a similar situation and the leak was comming from a burnt gasket...
