Oil Leak
 

Hi, new to the forum and have a problem. Just bought a 2000 SV 650S. Only 5800 miles and in excellent condition, but. Took it out for its first ride today and when got back noticed splashes of oil on rear tyre. Looks as though it is coming from a breather running down the rear right crank case by rear brake pedal. Pipe runs up behind right side panel and into a three way joint. One has no pipe on and the other leads to the other side of the engine. Can anyone tell me what this is and how to cure? :(
