CB750K5 breather pipe routes

<< < (2/2)

Roy,

Mine is a UK K6. Slight differences maybe? But, hope it helps.

The rocker box breather routes over the carb gantry, held under the frame (under the petrol tank) by a plastic tie and goes around and down behind the oil tank. It routes down to the right hand back of the engine case and is held by a metal bracket bolted at the top of the engine case, just beneath the right side rear engine mount. Then it goes horizontally back away from the engine, inside of the frame, under the swing arm, where it is held by a metal tie on the horizontal part of the frame that goes out to the rear footage/ exhaust bracket. It then drops down between the frame and the folded centre stand. The end is just below the height of the folded centre stand.

My oil tank is different to yours. It has a hose from the lower rear of the crank case, clamped onto the base of tha oil tank, which I had assumed was the breather. I also have two screwed on feed and return pipes.on the bottom of the tank.

The K6 oil tank is only for the K6 and is the only 750 that has that pipe routing .

OK. Apologies.
