its a "PAIR" Valve.

Its vacuum control (the pipe going from the carb) and it puts addition air into the exhaust for emissions.

With high temp sealer and an Ally plate you can block the hole in the Head.

If installing the FCR, you wont need the vacuum hose, so you can unbolt the whole system and simply pull it out.

I got worried when i took mine out, as it goes under the engine, Just pull. It'll come out!

Then your sorted!:censored:

another TT member made it for me, but its not difficult to do. He cut it by hand. then 2 holes and your set.

If your putting in the fcr you can just unbolt and and plug the head.

If your keeping the Mikuni, then you need to plug the nipple on the carb!

It wont make much difference, just reduce popping on decel!:censored:

Easiest way to make the blanking plate, is to remove the PAIR and use the flange as a template. :censored:

Here's what you need.

As you can see, the PAIR valve is gone, and the mounts are left.

This is where the PAIR Valve runs too, and where you need to block.

Just simply pull this part out from under the engine.

And here is what your making a plate for.
