Boyesen RC2 Series Rad Valve for Yamaha Banshees
NOW DESIGNED TO INTEGRATE WITH POPULAR OVERSIZED KEIHIN AND MIKUNI CARBURETORS!
Boyesen Engineering would like to introduce the all new RC2 Series Rad Valve is designed to increase power and throttle response performance in modified Yamaha banshees. The RC2 Series Rad Valve is Boyesen’s new performance intake system replaces the power-robbing, restrictive stock reed valves on Yamaha Banshees from 1987 to 2006, and can be purchased with all the kitted components to fit the stock/OEM intake system, or it can be purchased with a the required components to fit the following popular carburetion setups:

RAD VALVE PERFORMANCE:
The RC2 Series Rad Valve’s multi-stage reed petal system has been designed to increase throttle response and acceleration, while also broadening peak RPM horsepower output for a variety of stock and modified Yamaha Banshee setups. The RAD Valve’s seamless, one-piece, precision casting and continuous aero-form surfaces ensure maximum flow velocities and instant, explosive movement of air particles the moment you turn the throttle. Standard equipment on each RAD Valve, Boyesen dual-stage, Pro-Series Reeds have the superior ability to time themselves to the needs of the engine. You get maximum flow velocity across the entire RPM range, and at all throttle settings. Smooth. Sharp. Smart. The result: Full Spectrum power and throttle response. Dyno testing shows an immediate horsepower gain of anywhere from 5-10% through the majority of the Banshee’s powerband.
Each Banshee RC2 Rad Valve is Performance Optimized for typical Banshee configuration and takes into account specific Make, Model, Year, and carburetion setup options. Each Boyesen RAD Valve is unique – tailor made to that model, year and displacement. While other aftermarket valves might change flange sizes or bolt patterns, they’re basically generic – but with the RAD Valve, there are no compromises in power, no modifications. Result: A true, bolt-on Power Boost.
Simply remove the stock reed cage assembly and replace with the Boyesen Rad Valve system. All reed petals have been pre-assembled for easy of installation. The RC2 Rad Valve comes complete as a “Bolt-on Kit” and includes all mounting hardware, and gaskets.
The manufacturer’s suggested retail price of the Boyesen RC2 Banshee Rad Valve system is $289.95 (USD).
The Boyesen RC2 Rad Valve for Yamaha Banshee’s is available at your local dealer or popular web retailers. If your dealer has chosen not to stock this product, Boyesen also has made it available for purchase at our webstore. Visit www.boyesen.com for more information.
Rad Valve RC2 Technology
MAXIMUM POWER ACHIEVED THROUGH AIR INTAKE, ACCELERATION AND DISTRIBUTION
A year ago BOYESEN engineers embarked on a mission to create a new lineage of aerodynamic intake technology by refining the primary performance factors required to increase peak horsepower through design innovation: Aerodynamic Surface Optimization, Model-Specific Reed Petal Tensioning, Material Fuel Resistance, and Multi-Stage Reed Timing. Together, these innovations create a new technological benchmark in intake performance. The next generation RC2 Series Rad Valve results in an optimized reed valve system that provides superior efficiency, peak horsepower gains, and acceleration for YOUR specific model Banshee.
AERO OPTIMIZED INTERNAL SURFACING
Internal precision surfacing treatment eliminates all hard edges that interrupt with the proper delivery of air and fuel. The RAD Valve’s seamless, one-piece, precision casting and continuous aero-form surfaces ensure maximum flow velocities and instant, explosive movement of air particles the moment you open the throttle. Because internal air turbulence is virtually non-existent inside the Rad Valve, the proper air/fuel control is optimized for each make/model/year Banshee. This attention to the specific air and fuel requirements of each type of setup gives the RC2 Series Rad Valve the ability to reach consistent peak horsepower gains, optimizing power delivery for each specific application.
RESPONSIVE X-CROSS CARBON REEDS
The most responsive carbon reeds available for your Banshee.
Standard equipment on each Rage Cage, Boyesen dual-stage, Pro Series Reeds have the superior ability to time themselves to the needs of the engine. You get maximum flow velocity across the entire RPM range, and at all throttle settings. The Rad Valve’s Multi-Staged reed petal stacks feature aerospace carbon material interwoven into tension combinations that maximize power delivery and peak horsepower. Smooth. Sharp. Smart. The result: Full Spectrum power and throttle response.
The most durable materials. The most reed lifespan.
The RC2 Series Rad Valve now features category-leading toughening additives to increase reed petal lifespan by resisting breakdown from damaging agents found in fuel. In addition to our proprietary T2 Epoxy, the RC2 Series Rad Valve features rubber coated reed petals to ensure a long-lasting seal between the petals and the intake tract time and time again. Your customers will enjoy the durability of the RC2 Series Rad Valve season after season.
MS PLUS FLOW OPTIMIZATION
One reed petal is NOT enough!
The reed petals in Banshee engines take an incredible amount of abuse! At peak RPM reed petals are opening and closing hundreds of times per second. Over time, a single reed loses its ability to regulate flow rates in proper proportions. This causes a loss of reed petal reaction and reduces the consistency of peak horsepower. MS PLUS Optimization uses multi-staged reed petals to distribute the engine’s pulse forces over more surface area. By using a multiple reed petal stack, it is possible to achieve peak horsepower AND durability. The patented multi-stage design incorporates a specially shaped top reed petal and a ported bottom reed petal. The top petal is lightweight and resilient for crisp throttle response at partial throttle or low RPMs. The stiffer, bottom petal is ported to provide maximum flow and horsepower at higher RPMs.
