I am just curious why the Boyesen Rad Valve doesn't have a reed spacer option? The v-force may be thinner than the cage with the Rad Valve is the only thing I could think of but I have always wondered. Does anyone know for sure why?? Thanks

 

NCScrambler got a good point,the v-force reed cage is thinner so less bottom end but more top end,while the rad valve is larger all around for broader/stronger powerband,i tried both system with and without spacer
a new boyesen rad valve is on order for the upcoming season as well....
