Ok so Im gonna be putting on my bf's toomey on his blaster, motor is stock, gonna get Boysen dual stage power reeds, and UNI filter, but Im not sure if there is a difference for jetting for running no lid or with a vented lid, I kno the B1 exhaust comes with a 310 but Il need to buy prolly 300 and 320 just to be sure, so is there much of a difference between airlids??
