[quote="HKSRR"]Am I missing a hose here? top of front sprocket. sorry for ignorance.

HKSRR Yes there should be a hose on it, along with the other carb float bowl.
That is why the extrusion is there. You will notice the raised diameter on the end, so as the hose is retained in place when you attach the clips on.
It is a two-pipe arrangement that is joined at the bottom and exits with the other overflow and breather hoses on the right hand side of your bike, under the footrest hanger.
