Boost Bottles will not do anything over stock cross over tube
The idea of the crossover tube is to have some constant velocity from the carbs, Kinda like the one carb setup. But why would a boost bottle give your more air flow , even if its a 2 inch pipe there is still the two stock tube style pipes that go in the intake an dont let any more air flow than the stock pipe. It will change absolutely nothing to have a boost bottle other than rubbing on the gas hose and throttle cables and crack the intakes. And yes a bike will run fine with the intakes correctly plugged, making sure they seal fine.
