Oil leak after Pairs delete

[Andre]

A list of issues that can cause oil in the exhaust (with the potential of blow back into the PAIR):

The bike has had valve clearance checks in the past.  I considered most of the scenarios that Andre posted in that link, but other then the residue that's come out there are no other symptoms.  No power loss, no smoke of any sorts, fuel economy is normal.
When I first got the bike it was thoroughly check out by myself and a trustworthy mechanic.  The mechanic was impressed with the bikes mechanical condition and quality of ride.  There was no sign of contamination in the oil either.

One thought that I had as I right this, perhaps it isn't oil, but simply exhaust residue/soot combined with condensation?
I always got light blotting/oily residue around the end can of my CB500f, that was a brand new bike with solid service history and absolutely nothing wrong with it.  Perhaps it is the same residue, and  because of me playing with the Pairs I simply noticed it in an odd spot.

You are the best judge as to what it looks like.

FYI the dowel pins have their own gaskets.

Thats a crazy picture Andre, there is nothing like that in my pairs area, no actual liquid for that matter.  If you wipe it with your finger, residue stays on your finger, but i am seriously thinking it is soot and residue from normal exhaust conditions.
Wish i had of taken more photos, the plates are back on qith a bead of high temp rtv.  I'll let that set until triday ans report back on if the problem is solved

[Andre]

Sounds like normal condition then.

When I checked mine last year trying to solve an annoying problem I did not find any oil in the pairs system, is that how it's supposed to look or is that a bad condition?

[Andre]

Mick, you don't want oil there as in the pic. That's a bad condition.

[KiwiCol]

Was that in yours Andre?  What had caused it?

[Andre]

No Col, not mine. It was @rollerfish01 . Don't think he reported the actual reason. Had a damaged exhaust valve but not on one of the cylinders that belong to the PAIR valve in the pic. I guess new head and gaskets fixed it all.

Thanks Andre, after my poor running problem last year the bike has run perfectly and uses no oil so it's good to know that mine is as it should be.

Ok folks, quick update.  After applying the RTV and giving it ample curing time, I took the bike out this afternoon and the issue it totally gone.  Sucking noise is gone, exhaust note is silky sexy smooth, power delivery seems smoother too, no exhaust popping etc on overrun...   
I'm not too sure if there could be a better option then RTV, would it be better long term to sort out a custom gasket?
