Dangling breather/drain hose question

[MRMAICO]

I've just purchased an 86 R80rt and while riding yesterday I noticed a breather or drain hose hanging down close to the ground. It passes through the right side muffler/passenger footpeg mount and hangs down in front of the rear tire. Rather than just pulling the things apart trying to find where it goes I figured someone here should be able to point me as to where it is supposed to attach to.

Likely the battery vent tube.

Thanks Wes........It has a maintainance free Interstate in it now, there is no vent on it but I assume the original batteries must have had an overflow drain?
Thanks again..........Barry

There is a tank vent that goes down the right side.
On different models it goes different places but there should be a hole that it goes through around the passanger peg.
I think on the R80 it is the overflow from the well around the filler.
That is so if you spill gas it will not go trough and dump on the engine.

Thanks John, I'll check that tomorrow. This hose is pretty long to be a battery hose so your suggestion sounds more likely.

Just painted the battery box on the '82 RS yesterday.

The tube on *my* bike on the right (ass-sue-me you mean the throttle side) is an overflow hooked up to the rear brake fluid res.

Thanks Magwa, the RT has drum brakes though. It looks like it was the fuel filler neck drain hose although it was a little short for some reason. I just got a new piece of hose and put that on.
Time to go for a ride............Barry
