oil leak on crankcase

[cappyg]

Just wanting to know if any of you think this is the cam sensor oring or valve cover leak.  I am sorry I have not checked it yet since I just noticed it this morning.  There is a small wet spot about 1 inch forward of oil cap, but inside closer to cylinders. (right side of bike)  Not much at all, but I can smell it until it burns off.  Everything I searched seems that the other leaks are in the front by the header pipes.

Thanks in advance,
Greg.

The o-ring leak is quite common, so that's the first thing you'll want to check.  The valve cover leaking is much less common.

To clarify, the oil (wet spot) leak is on the back side of the cylinders forward of the oil fill cap?


Any oil on the cylinders?

I have a PHOTO but it exceeds the file limit size.  If you stand on the right of bike facing the crankcase.  The oil spot from dripping I suppose is about 1" to right of the oil filler cap but its back closer to the base of the cylinder.  A pic would be nice.  I have the pic here at work still trying to reduce the size of it.

Thanks again,
Greg.

photoscape is a free program that will do a lot of things with digital pictures, including reducing the size. Windows 10 I had to purchase it, but my 7pro machine it was free, and very easy to use.
Just trying to help so you CAN post a picture and get more info from those here that really know the bike.

Every winders comes with Paint.  Paint has a button called Resize.   It is that easy.

If the oil is not on the front of the engine but the back then it is not the sensor o-ring.

I just had a very similar leak. Mine turned out to be coming from the back of the rear brake master cylinder. The fluid reservoir under the seat has a tube that runs down to a plastic connector on the back of the master cylinder. The fluid dripped on to the exhaust heat shield, ran down the back edge and dripped right where you are describing. I replaced the snap ring, the connector and the O-ring (Partzilla.com) and it is now leak free. I am guessing heat from the exhaust damaged it. That's probably why Kawasaki extended the heat shield on newer bikes.
