Hi. I'm presently finishing up an engine for a CB77 build and have two questions regarding emission hose routing.

1. The valve cover emission line, I know this line travels down the back o f the engine and is held in place by a clip on the timing chain tensioner mounting bolt. From here, does the tube route underneath the engine case cover (one with black knob) and down the back side of the case, to vent toward the ground?

2. The two lines from the back of the head that are joined into a plastic Y connector, where does this route after coming together?


Minor details I know, just want to get it right. Thanks for any help!:)

The crankcase breather hose is routed as you suspected. It goes through the clip on the cam chain tensioner, then under the valley cover and toward the back of the engine.
The two outlets that go into the Y connector then lead to one of the small inlets on one of the air filters.

Got it! Thank you.

This bike is being built from a collection of parts w/o much for reference unfortunately.
