Motor oil leak under left side case cover

Hello, my 1600 has developed an oil leak. It appears to be coming from under or behind the left side case cover. I haven't had a chance to look at it as I just noticed it moments ago. Has anyone seen this before? Not going to be able to touch it for
two weeks but curiosity is killing me.

Sounds like the clutch push rod seal behind the cover. They can leak a little if they get worn. Easy fix by replacing with a new one. Just takes a little time.

I had that issue with my 1600 a few years ago.

Copy DesertDog288, that's sounds simple enough. I couldn't visualize what's behind the cover. I've only had that cover off once to flush the clutch fluid.
Thanks for the heads up.

get under and check exactly where it is coming from. If it is hydraulic fluid, then its the clutch slave cylinder.
If its engine oil, there is a weep hole in the middle of the crank case that warns you the oil seal behind the water pump is defective.

Copy, sunnybob thanks for the heads up. I'm quite sure it is motor oil. I'll be pulling the cover off in the next couple of days. Have you replaced that oil seal before?

clean the bottom of the engine cases, dust baby powder all over them, and go for a half hour ride.

The baby powder will show you exactly where the oil is coming from.
If it is the small hole (about 3/8" diameter) just to the right of crankcase centre, then its a serious issue.

I have never had to replace that seal. The factory book says the engine has to be totally stripped to replace it from the inside. But I have heard of good results by someone's kit that doesn't need so much work.
Its been a while now, but I think the adaptor seal is made by chuckster. surf for that.

If its from somewhere else, then still the baby powder will still show you the way, and hopefully it will just be a gasket.

Had this happen some years ago and just put silicone around the seal, make sure you don't get any on the rod. Clean the area well I used brake cleaner, drain some oil so it is not going to mess the area up. Push it back into the case making damn sure you don't go too far. Let it cure and your done. Top oil up.

Rusty, your fix is for the clutch slave cylinder seal. It looks like iamarchie has a an oil leak on the water pump shaft.
I expect he'll let us know when he's found it.

It's cold in the garage!

I haven't pulled the cover yet its cold out there, but im ready to crank up the propane heater and the stereo in the garage. I am greatful for the insight, thank you. I'll post what I find.
Also im using the Barnett heavy duty clutch spring. Any thoughts about the Mean Streak vs Barnett's.
I'm going to throw in judges Washers.

Finally! I got around to my oil leak. It was the rubber o-ring seal on the clutch rod. I'm glad that was it. I cleaned the seal up and the area where the seal fits. I carefully pushed it back to flush and applied a nifty amount of high temp rtv around the o-ring.
Also Applied grease to the rod.
I'm surprised at Kawasaki's design, just seems odd, or half assed. But what do I know.
I'm waiting 24 hrs for the rtv to set up.
Thanks for the input.

I had the same problem with Rosie last year.
What I've been reading is that sometimes the seal just... moves :)

I used the same fix and have ridden about 200 miles so far with no leaking since.
