The engines getting hot you need the right amont of oil to cool the engine , it has to b the rite oil too,go to your loacal bike shop and tell them your bike details,ok

a leak in the valve cover gasket. When oil leaks from the valve cover gasket, it will often burn off on the manifold.
a blown oil seal causing oil to burn off on the exhaust system
check your exhaust for "blue smoke" a sign that the engine is actually burning oil. Just guessing here but a 16 year old Volvo is bound to have quite a few miles on it.
I hope you found this post helpful in diagnosing your problem. Thank you for using Fixya!

This hose should be connected to the air filter box.
It's for ventilation of the crankcase, much like the PCV (Positive Crankcase Ventilation) in cars. As the bike runs, the crankcase gets hot enough to vaporize some of the oil. And since there's always at least a little bit of combustion blowby in the cylinders, you get a bit of fuel/air thrown into the mix and an oil/fuel/air "atmosphere" in the crankcase, which isn't an ideal situation. So, when the hose is connected to the air filter box, it slightly vacuums off this atmosphere, letting the engine burn it and expel it through the exhaust.
If it's not connected to the airbox, the vapors can condense back to oil and just drip out.
If a lot of oil is coming out ("a lot" is hard to quantify), you could be getting excessive blowby because of a broken ring or cracked piston.
Hook that breather line back up to the airbox and unless the bike smokes excessively, I wouldn't worry about it.
If it IS hooked up, it or the airbox is cracked and needs fixing/replacing. If the breather line has somehow become plugged (mud-daubers are amazing at finding holes to makes homes out of), the pressure buildup could have split your vent line.
adding a performance exhaust system to most motorcycles will boost horsepower 3 to 7%. If the motorcycle is carburated, a larger jet and a high flow breather (filter) will help to gain the maximum.
Start with making sure your oil lever is not over full. If it is it may be getting into the crankcase breather hose that goes to the carburetor hence the white smoke. Sometimes also you can blow a gasket in the breather system and it will do the same. Check for oil leaks in the breather system. Hope this helps. donnyb60
