Description
Stock intake manifolds compromise flow velocity and throttle response—the Boyesen Radiator Valve fixes both. By maintaining charge velocity through the valve and redirecting intake flow for even distribution across ports, this part delivers sharper throttle response and measurable horsepower gains across the entire RPM range. If you’re serious about extracting every bit of performance from your RM80, this is a must-have upgrade.
The engineering is straightforward but effective: Boyesen’s patented dual-stage reed design, housed in a specially-engineered reed cage, optimizes intake dynamics while the one-piece cast aluminum construction makes installation a simple bolt-on job. Order one set per cylinder for your application.
