the reed valves only open and suck in air on deceleration, to burn off extra unburnt fuel when you shut the throttle down, when you are cruising or at full throttle the system is shut down so exhaust wont go up threw the system, so by doing this mod you will be sealing your crankcase at cruising and full throttle runs, this is very bad for horsepower and will probable blow some oil seals quickly. examine how the reed valve works!!
