Can somebody show me a picture of a rear breather tube so I can see how it looks like? I had a rear valve oil leak and the dealer said they change the breather tube. When I came home, I have the same problem. I opened the airbox cover and I can see a corrugated tube that is clamp to the top of the rear valve cover. Is that the rear breather tube? If so, it has a lot of cracks. I supposed the oil leak is coming from there? Thanks
