Yamaha - Oil Pipe Lubrication System Component 6K7-24319-00-00. Overview. The Yamaha Oil Pipe 6K7-24319-00-00 is one of those small parts that carries a big responsibility-keeping oil moving where it needs to go. When these lines start to crack, clog, or loosen up, you can end up starving the engine of proper lubrication without much warning. I've seen engines go down over something as simple as a compromised oil line. Keeping this pipe in good shape is key to making sure your motor stays protected every time you run it..
