Ive got both sets, the single stage and dual stage reeds from my older KDX and have just bought a 98 200 with a gnarly torque pipe. Does anyone have any idea which set would be best to smooth the power hit as its still a bit 'switch like'. :p
It makes sense as with lower revs there's lower pressure and the first stage will open nicely. The single stage are in my 89 SR and they gave it a better hit than the dual stage. So if you want to tone the powerband down use dual. If you like a hard hitting band then go for the stiffer single stage.
