Question Mystery tube coming out if engine...

     

There is a black tube coming out of the engine on my 1994 CR80R and it is not plugged into anything just hanging. I couldn’t find any place near the end that it might attatch to. Is it supposed to be hanging like that? Any help is appreciated. Thanks! Pictures>>>.

I believe your photo correlates with part number 6 on this diagram

As for what it is, and what it does, it's the bike's crankcase breather tube. When the bike runs it creates some oxygen/air inside the cavities of the engine, which can sometimes force minor amounts of your transmission oil out when the engine expels the excess oxygen/air. Sometimes the manufacturers rout that tube into the airbox, but it looks as if Honda decided on those CR80/85's to just rout it out and down by the bottom of the frame and just let whatever little transmission fluid to leak out onto the ground, instead of oiling up your airbox

At least to my understanding, I am no mechanic lol.
