I am sure that it is off the back of the filter housing near the bottom, I have both mine off right now and so can not say 100% sure, but I am thinking so. I have never seen any oil coming out of it, but have seen oil collected in the location of the opening in the housing, and wondered about it. Same as the milk bottle.....lol......never seen one full but after a summer I have seen one about half full.....

I'm pretty sure (before I wiped up the fluid on the floor) that it wasn't gas but oil, so it's reassuring what you're saying above, that it's not a leaking gasket or something serious. BTW, just came off a 120 mile ride this afternoon and there's no sign of anything coming out that overflow hose... Thanks.GB I think he is talking about the hose that comes from the back of the filter housing and passes through between the jugs and then through the area behind the drive sprocket and hangs down along the oil sight level.......now someone has fixed that so the oil that drips from there went on to their chain. I think that is just a drain for the oil that blows past and comes into the air filter housing......

If so, that is basically the container for any oil to accumulate from the crank-case vent system. The stock system is messy - if I remember it makes a mess through the air cleaner system etc. A lot of people remove all that stuff and just put a hose to the ground.

The only reason I ask is because For the First Time I noticed it because the first time there was some oil on my garage floor from it after about a one-hour ride. Actually I wiped it up so quickly I wasn't even able to confirm that it is oil and not something else. Pretty stupid I know and also stupid that I am not able to really Trace where it comes from on the engine. But anyway that's why I have you guys the experts who inform me, thanks for your help.
