I have a 1999Kdx 220 with a modified air box, a FMF torque pipe and power core II silencer. If I put in Boyseen reeds or a Moto Tassinari v-force valve should I change the stock jetting on my bike from a 42 pilot jet and 145 main jet to a 40 pilot jet and 142 main jet I ride in New England ? Also which is better a Moto Tassinari V-Force valve or a Boyseen Rad valve ?
