    This is not an Economy Cycle recommended part. It works fine, but we've had a number of complaints about the manifolds not lasting longer than a few months. We are discontinuing this part,  have a few sets remaining at a reduced price. 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

Carb side opening i.d. accommodates 35mm carb spigot. (recommended for use with stock 28mm carbs on RD350/400 or RZ350 applications). Perfect for use with boost bottle.
