2005? Pantera 125

[Thedude4355]

So, this old bike was sitting behind a neighbors barn under a tarp. I've cleaned it up, and I can fire it up, but as soon as it starts it throws oil out of a vent on top of the crank case, under the carb. I'm sure it's supposed to be a vent, but I'm not sure if it requires a valve? Like a PCV valve on a car? Or is it just meant to have a hose on it? The rubber hose that was on it was rotted off and isn't anywhere to be found.

Overfilling could cause this
Drain the oil (overnight!). Replace with 900 to 1000 mL of a good clutch friendly oil. Then try again.

...And run the (missing) crankcase breather hose down the back of the engine between the frame and the swingarm

I had one of those, bought it from PEP boys for $999. I ended up putting a 200cc engine in it and turning it into a cafe racer
