Why is the oil breather hose in the airbox?
It is why you have the breather hose to the airbox and the drain tube in the first place. It keeps the oil pressure in the engine from reaching critical levels & blowing out a gasket. I assume that the machine is running well, with no loss of power or compression in conjunction with the oil problem, or you would have mentioned it.
Why is there oil in the breather tube of a motorcycle?
by Chris Gilliland. A stream of oil, flowing from the engine’s breather tube and into your motorcycle’s air box, is the result of a condition called blow-by. Caused by an increase of pressure within a motorcycle’s engine, this phenomenon forces oil up into the breather tube attached to the crankcase.
How do I change the oil breather hose?
Replace your current hose with one that is a few inches longer. Route it in such a way as to make it go up higher before in comes back down to the air box. Just take care not to kink it. This will enable the oil to drain back into the engine after an aggressive acceleration or rapid deceleration.
How does oil get out of the air box?
Then it will migrate through the breather hose on the air box. Once there, the only way it can get out is through the drain tube on the bottom. This is what is supposed to happen with motor oil. It is why you have the breather hose to the airbox and the drain tube in the first place.

What do you need to know about engine breather system?
These tanks should have a minimum 1 litre capacity, 2 top inlet connections (1 crankcase vent and 1 valve/cam cover vent), a sight gauge (to indicate the level of any oil inside) and a bottom plug or tap to allow the oil to be drained off when necessary.
Why do I need a breather filter in my tank?
They keep contamination and water from any connection with fluctuations of the oil level in the tank (tank breathing). Ideally, these breather filters should have at least the same filtration rating as the filters in the lubricating and hydraulic circuits.
Is there oil in the air filter box?
The oil level is correct, the bike sat over the winter but was crancked every month but maybe one or two. when I remove the air filter the bike will run, but the hose still blows oil out. I have cleaned the air filter, but it quickly coats wilt oil when the engine runs. Any suggestions on trouble shooting/repair needs.
Is the breather tube from the top of the motor?
My question is the small breather tube from the top of the motor to the air cleaner box exit it’s close to the carb. and puddles some oil in the air cleaner box. Is the carb supposed to suck oil up through the tube or is there some type of defect in the breather system The motor runs strong, Good compression, No exhaust smoke.
