I have a 2015 SESG. I was using an excessive amount of oil. So several weeks ago I see a drop of oil on the cam cover. Further investigation removing air filter shows oil dripping off back plate and lower filter drenched in oil. Go to dealer they replace umbrella valves. So a few weeks goes by. I check oil again and see I am using oil again. Also back plate dripping with oil again.

So gonna go back to dealer. It's still under warranty. Not being a motor guy I wanted some input as to what the problem might be. And what the dealer should do to repair. Thanks in advance for any advice.

By excessive, do you mean your using up oil and have to add? Or it's leaking, spurting out? Might be you have too much oil and it's flowing back

Could be bad Rings,,,

Yes to using oil and have to add. The only place I see oil is some drops on cam cover. But also dripping off air filter back plate and bottom of air filter.

You never say how much oil is being lost.  Quart to how many miles?

I'll go through more than a quart in a thousand miles.

Im pretty sure your not losing that much through the filter.  I hope your dealer isn't like others mentioned on here that say that is normal. 

Mine has always had a puking problem. I run about .25 quart below max fill line and this seems to help. 

But that's probably minor to where the oil is going.  Do you see smoke from exhaust?  Is your exhaust bad sooty?  Is primary oil level remaining normal?

Yeap, obviously excessive; and obviously considerably more than you'd have just coming out of the breather (at least not without an oil slick down the side of the bike).  Definitely time for a leakdown test of one hasn't been done.  No need to speculate when you can find out that simply.

Primary oil level is fine. I nor my friends have seen any smoke from  exhaust. Oil on cam cover, on rear cylinder exhaust heat shield and dripping off underside of air filter.

It sounds like you guys are suggesting rings?

Not suggesting any one specific thing.  As much oil as you describe is unlikely to be leak or breather related without showing more mess than I sense you're describing.  If it's not all outside the only other option is inside.  That could be rings or valves though.  Many problems reported with guides and guide seals in recent years.  The only thing I actually know about your engine is I don't know anything about your engine.  Having said that I also know a simple leakdown test, done properly, has to point you in the right direction.  It's easier, faster, but often less fun to actually diagnose and test than it is to guess online  .

Thx so much for your ideas and input.

I had a similar problem with my 11 CVO Ultra & the blow by would be on the pants of my right leg.. Dealer installed new umbrella valves & I routed a breather tube down to a catch can. There is a thread on how to do the breather upgrade. It is simple to do! Also the 110 motors don't like to be lugged!  So if you are running below 2800 to 3000 in sixth gear you're lugging the motor & is going to push oil out the breather & down on your nose cone & exhaust. Shift to 5th gear  & run the higher rpms & your 110 will run better & not be dripping oil out the breather. So far it has worked for me.

3 possible causes for oil coming thru A/C (breathers):
1. oil tank over filled (fill to proper lever or just below)
2.blow by from bad rings (leak down motor,bore top OS pistons/rings,i wouldn't just re-ring it)
3. sumping (run,then drain lower end to see how much comes out,should be no more than 4-5 oz,this can be caused by a bad pump seal or crank out of true to the point of causing pump damage)

Thx very much excellent ideas.
