Description
If you’re running a RM250 two-stroke, intake charge distribution directly impacts throttle response and mid-range power delivery. The Boyesen Radiator Valve optimizes flow velocity through the intake tract, ensuring an even charge distribution across all ports for sharper throttle feel and measurable horsepower gains across the entire RPM band. This is a bolt-on upgrade that delivers real performance without custom fabrication.
