Boost bottle or crossover

[78rd420]

Hello what would be better for rd400 mild motor,portted,carbs,crossover tube or a boost bottle?been trying to get a hold of Chuck and have no response for a boost bottle and it's time to finish my bike so I could get a crossover tube like on a banshee or I could get a boost bottle from somebody else? What is best?thanks

you can use a crossover, its good. chuck will be back, eventually, but in the meantime use a crossover tube. do NOT use a big banshee bottle on a mild street bike
