There is a T fitting coming off the carbs, the vent tube runs off of that. You can just tuck this down under the tank, (facing down). Some have routed it to a small crankcase filter but it doesn't need it, just so it gets good air flow without catching a bunch of debris.
I think Pick had his close to the edge of the tank and discovered if he happened to hug the tank with his knees he got a little sputter. Of course knnes came away from the tank when he looked down and it smoothed out.. Once he rerouted the hose it was smooth sailing at all rpms.
