BOYESEN Reed Valve for KAWASAKI KDX 200 1989-2006

The BOYESEN BOYRAD-14XA reed valve block is designed for KAWASAKI KDX 200 from 1989 to 2006. On a two-stroke, the reed valve block sits between the carburettor and the engine. Its petals open under suction and close again as soon as the pressure reverses: the engine's pick-up and power depend on how quickly they react and how much air gets through.
