I've got an oil leak on my 2013 originating from the left side near where the kickstand attaches to the bike (see attached images).

Most of the oil runs down the kick stand and puddles up at the bottom of it. There's also a smaller amount that runs down and drips off the oil pan directly underneath the bike. It only leaks when the bike is running and for a short time after it stops.

It looks like the source is near where that big hose (not sure what it is) connects in right next to the shift lever. Anyone have any ideas for diagnosis/repair?

Thanks!

You are going to have to clean all that **** off real good, and then watch the area very closely while the engine is running, to try to pinpoint the origin of the leak. Good luck to you.

I second the cleaning advice. Oil can travel far from where it's leaking from pushed by the airflow when riding.

Use degreaser and get the area around there looking near showroom.

I've even taken to blowing a light coating of flour onto my cases at times as this really allows you to see how the oil is moving.

It's a bit of a pain up front but otherwise you're guessing and potentially fixing what ain't broke.

are you sure that's not excess chain lube?
You should have seen my CBR after a few years ;) I'd agree with you except...

"Most of the oil runs down the kick stand and puddles up at the bottom of it. There's also a smaller amount that runs down and drips off the oil pan directly underneath the bike. It only leaks when the bike is running and for a short time after it stops."

Doesn't sound like chain lube, but like Bat-1 said, clean the **** outta the whole area, and try to reproduce the issue.

To appease Tary and myself, what kind of chain lube do you use, and how much and/or how do you apply it?

One more thing, check your oil level in the sight glass. Is it lower?

I have the (3) open ended rubber hoses routed out from under the plastics via the hole in the fairing near the kickstand. Pretty sure this is the OEM routing. Bike is too new to me to know where they come from, but I'm fairly certain they are fluid drains. Guessing crankcase breather, coolant overflow, and maybe a seal drain (?). I would clean it all up and tie a small plastic bag to each of these hoses to see if it's coming from one of them. If it is, monitor the rate of drainage and determine if it's a big enough issue to worry about. If they were routed properly, the oil would drain overboard rather than underneath the plastics were it can collect.

none of those drains have anything to do with oil. one is the fuel tank breather, the other is fuel tank overflow, and the last is coolant expansion tank overflow

I clean my chain and sprocket with kerosene and then lube it with Maxima Chain Wax. I originally had thought it could be excess chain lube/gunk coming out from the front sprocket but it's definitely not. My chain is pretty dry right now, it's been about a month since I cleaned/lubed it (go ahead, judge me), yet the leak is still steady.

Oil level has dropped down a little bit but not substantially. The leak started about a month ago and oil level is still about 1/3 of the way up the sight window.

I bought some degreaser and a wire brush yesterday so I'm going to get the whole area cleaned up so I can hopefully track this source down a little better. Will update.

Thanks for the suggestions!
