Hello Luke, welcome to the site.
As Gary said we would gladly help but need more info/pictures.
In the carb area you could be referring to the vacuum lines from the intake manifolds to the petcocks or the crank case breather tubes or ???

The '81 had a single petcock(L) with a vacuum line going from the nipple on the intake to a nipple on the back/inside of the petcock. The right side will have a plug/boot on the intake manifold.
As Yamaha delivered it there was one vacuum line from the LH intake just in front of the carb up to the back side of the petcock. There is a port on the RH intake also but it should have a cap on it.
Your bike has after market carbs.
You need the VM carb guide.

Hi Luke,
those yellow plastic tubes are the fuel feed. The single tube comes down from the gas tap on the aftermarket gas tank, the blob in the middle is an in-line gas filter and the plastic Tee splits the gas flow into two, one tube to each carb's gas connection.
Looking just below the in-line gas filter you'll see a small black rubber cap that's blocking off a metal tube that's sticking out of the carb-to-engine adapter piece.
That's the vacuum connection. There's another one on the other carb's adapter.
They were used on the stock bike to work the vacuum operated stock gas taps that your bike don't have any more.
They are blocked off so the engine can't suck in extra air through them and screw up the fuel mixture.
Their other use is for hooking up vacuum gauges when balancing the carbs.

this should get you pretty close.
