Replacement RD250/350/400 Carburetors - Mikuni VM Round Slide Series 28mm Carburetors (pair). Original carburetors for the RD250/350/400 are no longer available from Yamaha. However, Mikuni does offer new VM28 round slide carburetors that are very similar in function and appearance to the original RD carbs. They do require re-jetting, a new throttle cable and optional oil injection. We include a 2 line cable for bikes that use premix or a 3 line cable if you choose the oil injection option. The oil injection option includes new oil nozzles. These carbs are only available with left hand idle screw and have individual choke levers (no choke crossover between carbs). We can jet the carbs for a stock RD250, RD350 or RD400 or for your specific application if you have pipes and other modifications that require jetting changes. Please submit a note with your order upon checkout for jetting changes required, if additional information is required we will contact you. Carb sets are built to order, please allow 5-10 days for shipping. You should let us know the year/model of your RD and any modifications, pipes, air filter, porting, etc. Note: The oil injection option is not required for the R5/DS7. -

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 -
