That is a a way.
I found the occasional engine stumble and pop would cause the seal to leak eventually..
So I drilled and taped threads in the valve cover hole for the pair system and installed a threaded plug

Back to PAIR. I'm wondering whether that O ring and Collar are needed if earlier Cam covers are put on.

The small Collar and O ring lead to hole drilled into the exhaust port so the injected air can get into the exhaust system.
I'm not sure if your early models have the hole drilled but if installing on a bike that has the PAIR removed they will be needed or you will have either an exhaust leak into the valve cover or a direct path for oil to leak into the exhaust if you do not install the collar.
I've run mine for the last 14-15 yrs with the reeds flipped, covers installed and the collar in place with no ill effects so far

If you drill & tap the hole in the head below the valve you can locktight a headless bolt / screw in there & the problem is curred. Dont let any swarf go down into the exhaust port!

Personally I would just flip the reed over & bolt it all back down using the blanking plates supplied in the kit. Below is the kit I used:
This is the exhaust feed that runs from the exhaust port to the reed valve in the cam cover .
This is the pair cam cover in side view
That looks just like the non pair cam cover
By having. A good look today the old cam covers will fit and there will be no need for blanking plates .

Right o.. good job..
SO you'll only have that one O ring left that could leak..
Were it me.. (and it was) drill and tap the passage in the head... screw in a socket head tapered thread plug, and never again think about it.. the exhaust passage for the PAIR will be sealed forever.

looks like it and i do like the idea of permanently plugging the exhaust feed hole but as its not my bike i wouldn't attempt it .if it was mine then yes id plug it .
for its owner an O ring is easy to change the same time as the valve clearance check so its not that much of a issue .
I can confirm that replacing the cam covers for non pair type and blocking the hole in the air box bottom and also blocking the small vac feed to the pair gizmo works .
Might be easier than trying to get the kit from the USA :-)

Can someone explain to me where the "O" ring and collar are? If I put the blanking plate on the valve cover where are the afore mention bits in relation to that? And how does the oil get into the airbox if these are left out?
Cheers
