I have a stock blaster that I just bought some Vforce4 reeds and a toomey b1 silencer for. I will be using the stock header pipe for now and the air box lid is off. What size jets should I start out trying?

The reeds and silencer don't have much effect on main jetting.
The airbox lid off will as you will be increasing air flow. Ussualy 1 to 2 size increase us required.
But 2 other things need to be taken into consideration.
Temp. Is very important.big temp changes require rejetting.
Altitude is also a factor.
Without. Knowing what is in it already for jetting, temp, and altitude . and was it jetted correctly before?
Also assuming stock carb?
