Hey Stoney,
The vent lines can be routed a number of different ways and still be effective. The "T" you are asking about
generally is off the right side of the carb. If you rotate the T 90deg. clockwise, one leg runs up under the backbone of the frame near the coil. The other leg drops down with the crankcase vent over the swingarm.
The left vent or overflow is usually routed towards the shifter and secured by a small line holder that uses a bolt from the magneto cover to keep it in place. If this doesn't make sense I'll look for some piccy's.
