Oil in air air box hose

[sws564]

Hello, I took my air box off and noticed some oil in the large line off the valve pictured, there is no oil collected in the air box. Is this normal or will this need to be cleaned/replced?

Normal. One-way breather valve. Think of it as like a PCV valve on a car/truck engine.

Could stand to be cleaned every so often.

Thanks, what should I clean it with, carb or brake cleaner?

Yep... lol. Either or I'd say. Both cut oil/grease.
