CB750K5 breather pipe routes

(1/2) > >>

royhall:
Just come to fitting the breather pipes on the K5. The bike didn't have any pipes on it when it arrived so I have no idea of the routings. Any pictures available at all, or explanations. I need the rocker box breather, the crankcase breather, and the oil tank breather. Also, on the bottom rear of the oil tank is a small 6mm ish pipe that looks like a breather, what does that connect to. Thanks.

There is no crank case breather. The pipe on the back of the engine goes to the oil tank. The top rocker cover breather pipe goes to atmosphere over the top of the air box and down the back and also the overflow from the oil tank goes to atmosphere.
Or you could have it like the K6, were the top breather pipe runs along the swing arm and had a little bracket on the back of the footpeg bolt.

Thanks Julie your a star. Just to clarify that I have it right, the top breather on the oil tank connects to the rear crankcase spigot, and the little spigot on the oil tank is an overflow to the ground. Cheers.

The little spigot on the oil tank goes to the spigot on the back of the engine. This feeds oil for the chain oiler.
