Includes 2 New Manifolds with Reed Stuffers, Cross Over Hose and Clamps. The Cross over tube helps with mid range performance and helps to smooth power delivery, eliminate flat spots, stumble, bucking, etc. Most of the later Euro/Canadian RD400's and the RZ350 had this type of intake set up, but was never available in the USA. The cross over tube is high quality reinforced fuel hose for long life. The tube bends in an arch between the manifolds. Unlike most aftermarket manifolds for RD's, these have reeds stuffers like the original manifolds (reed stuffers are the rubber ears on the backside of the manifold that stick into the reed cage) Reed stuffers improve performance by increasing intake velocity while reducing turbulence, improves throttle response and increases bottom end and mid power
