Can anyone help me I'm trying to put a new air filter on my coolster 125cc pit bike and I have a hose coming out of my air filter connecting down to the top of the engine? I bought a new foam air filter but it doesn't have a connection for a hose. I was told the tube is for a crankcase breather but I'm not 100% sure. Can I still use my new foam air filter and if so what do I do with the crankcase breather?
