You change the secondary metering rods. The taper of the rod coming out of the fixed office make it act like a different sized jet. Cruise should be on the primary side of the carb so not much is going to affect the milage other than proper mixture screw settings. The throttle blades are about the size of a dime on the front barrels so they run real lean as it is.
