The BOYESEN BOYRAD-24K reed valve block is designed for SUZUKI RM 250 from 2004 to 2011. On a two-stroke, the reed valve block meters the mixture into the crankcase. A complete reed valve block replaces the original cage and petals in one go.
Check the petals at every piston change and replace them as soon as a tip is chipped.
Boyesen is an American brand specialising in the intake and the engine covers of two-stroke engines: reed petals, RAD Valve reed blocks, engine covers and Supercooler water pumps.
Do I need to change the jetting?
Usually not; check the colour of the spark plug after the first few rides and adjust if needed.
