It is a 1995 wolverine 350, I am in Utah and it is gas. It was running fine then my friend and I saw that the drain was disconnected. I don't know much about four wheeler's, but my friend does. It started when he put it on but it was backwards. and the black hose goes from my engine to my carberator.

If you are up for it, buy a manual ($15.00 from Amazon https://www.amazon.com/Yamaha-Wolverine-Service-Maintenance-1995-2010/dp/B00JEK87GQ/ref=sr_1_1?ie=UTF8&qid=1467944445&sr=8-1&keywords=1995+wolverine+350+manual). Most manuals will have the actual names of the parts, what they do, troubleshooting, and how to fix them. When it comes, grab your friend and work through the sections that include the crankcase vent.

Also, take your question to an ATV forum like Yamaha Wolverine 350 / 450 http://www.bluetraxx.com/forums/yamaha-wolverine-350-450/.

It sound like this is a crankcase breather pipe which normally feeds into the air inlet or the top of the crank case.

i guess the fluid is black oil and you have fixed it.

If you cannot identify the liquid, or the orifice from when it came, take the infernal machine to a professional.

There is wisdom in this answer.

Erm, there is also a typo in it:

But more importantly, there may be something to this notion that knowing the names of the fluids, and the names of the parts of the engine and such, that this knowledge is a prerequisite to being capable of fixing the darned thing.

Almost sounds like a four cycle leaky valve.

Or bad rings. Or an out of round cylinder. Or a blocked oil return. Or bad timing. Or if it has been mudded or swamped….

Could just be condensation, perhaps the black pipe is the exhaust.

leaky aircon overflow

Any number of seriouc fluid leaks.

Your correct about all the failure modes.. Four wheelers around the high desert, where I live, get into sand a lot.

Maybe after a good first cleaning and an oil change, Chase22 will let us know more.

Age, type, service record, second hand and where in the world could help the diagnosis :-)

OIL

GAS

Or water

Or a mix of water and oil?

It makes a big difference.

Type and make of vehicle

Exactly where is the liquid coming from

Does it run well otherwise
