  • Boost Bottle for RD250, RD350, all years, RDLC350 1980-1982, RZ350 all years, Banshee all years. Increased performance, throttle response, carb balance, stores fuel charge for additional power. All Aluminum body with leak proof nipples. Approximate dimensions 2 in. x 6.25 in. Requires cross over type manifolds (RZ style - sold in our manifolds category product 005-835 for stock 28mm carbs,  or 005-836 (by UPP) for 30-34mm carbs, or 1050-0057 (by Moose) for 30-34mm carbs). Note: Not recommended for RD400 as there is not enough clearance to fit the bottle.
  • 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
  • Manifolds for 26-28mm Carbs(VM, TM, PWK, PJ) with Boost/Crossover holes. Mfg'd by UPP, high quality polyurethane, outperforms stock manifolds.

  • Yamaha RZ350 Reed Block Spacers Billet, Plain (pair). Machined from 6063 T6 billet aluminum. These spacers are 9mm thick. Why Reed Spacers? Basically, reed spacers allow you to move your power band around depending on placement. The most common installation for street use is to mount them between the reed block cage and the engine. This will effectively increase crankcase volume and move your power band to a lower rev range, allowing you to make better use of the power available for street riding. The second type of installation is to mount them between the manifold and the reed block cage, increasing the intake tract. This will move the manifold back further and raise the power band for better midrange and top end. Individual results will vary from bike to bike depending on intake set up, air filters, jetting, porting, exhaust, etc. We also carry new RD/RZ manifolds, both the regular stock RD manifolds and RZ manifolds with cross over tube. Stainless or black manifold Allen (cap socket) bolts available in longer lengths to accommodate these spacers (in the bolt kit category). Not recommended for use with stock air box).
