Oil leak after Pairs delete

[Masterbates]

So today I rode my bike for the first time after the Pairs delete, it is a little bit smoother but I can hear a slight sucking noise from the right hand side. 
I am guessing the blanking plate isn't evenly torqued down.

But the concerning thing was the screw directly behind the blanking plate had oil on it.  There was also a slight splatter on that side.
Now I definitely didn't touch that bolt during the Pairs removal...  how concerned should I be?

Clean it off with a bit of de-greaser, give it a nip up (to the appropriate torque, which would be?) & see if it returns.

When you fitted the blanking plate did you refit the rubber seal off the pairs plate you removed (on the blanking plate inside)  or put any sealant on the joint?

Im not familiar with the kit you used, on my one, you had an insert to replace the inner plate and then a replacement cover. The seal I mention needs to go on the inner plate. If you didn't get one, then that could be the issue, no worries, assuming you still have the original inners, refit them with the reeds removed (but keeping the seal) and then refit the outer cover from your kit.

I suspect you have a slight blow of oil onto that bolt from not having a good seal on the cover. In the first instance I'd suggest having that blanking plate off again and checking the seal.

Thanks guys, I used the Smart Moto kit that has been mentioned a few times here.  I simply removed the reed valves from the inner plate and then put the plates back in.  No extra sealant was applied.
There is no oil coming from around the plate, it is exclusively coming from that bolt aft of the blanking plate

I'll nip that bolt up like @KiwiCol mentioned and maybe reseat the blanking plate

Ok now i'm thinking.....l just blocked the hoses. Should l have taken the reeds out ??

[Masterbates]

Ok, quick update.

Got home fine and already have the tank off, i think as @gsxbarmy suggested it is a slight blow of oil.  There was a little on the left side but forward of the plate. 
I have removed and reseated the plates.  Both sides have the original inner plate and seal with the read valves removed.

Just took it for a run and it is still making the noise and blowing a little oil.  Any recommendations for an RTV sealant or some such?

Nah, just blocking the one that goes between the pairs unit & the covers is fine to do.  Did that on my black & ripped the whole lot out on the blue.

Nope. If you just blocked the hoses the reeds can stay.

Not too sure what is available down under Masterbates, in the UK, something like Instant Gasket made by Loctite would work ok.

I'm surprised though that it is still blowing. What you could try is to screw a suitable sized allen bolt into one of the original covers and fit that on the side that is blowing. If it stops blowing then  the new cover has something wrong with it, a bit of mucky maybe, or a scratch, slight bend?  or similar. Or maybe try swapping the new plates over to see if the problem transfers.

There should not be any oil in the PAIR system at all!

Only way oil can get there is a defect head cover gasket or a crack in the passageways. Also I seem to remember that the dowel pins (see attached pic) serve as "channel connectors" for the PAIR. If the Head cover was off, one or more could have been "lost".

[Masterbates]

I did have that thought @Andre, but I was also thinking it might just be a result of blow back in the exhaust gases? 
The bike isn't losing oil in any measurable quantity and without any air entering the pair valve chamber directly any residue in the exhaust gases will end up in the Pair valve chamber.

To the best of my knowledge the head has never been off the engine.

[Andre]

Oil is not supposed to be in the exhaust gases. If it does there is a problem that needs to be addressed. All you should find in the PAIR valve chamber is what you normally see in exhaust pipes.

Ah - but the cam cover might have been if the valve clearances were checked at some stage.

What I find odd though is that this has manifested itself by removing the PAIRS system, as, as Andre says that should have no impact as there shouldn't be any oil in that area.

[Andre]

It is odd but the oil may have been there before and now comes to attention due to ineffective seal of the PAIR cover.

Thinking the only other way any oil could get into the pair's valve area would be if the valve stem seals were weak or leaking .
Not sure if this is even possible due to the heat in exhausts .
