tube on frame

[ac@39]

Hopefully not a daft question as i cant see it on the schematics for the frame. On the left hand side of the bike as you sit on it, on the inside of the frame and next to the carbs there is a tube that is part of the frame , i assume this is some sort of breather but -- what is meant to connect to it?

connects to a little spiggot on the bottom left corner of the airbox

Yep, also have one each way. My '96 has it, but my '99 does not.
