only left side banshee carbs have the choke knob, and a tube that supplies choke circut to the right side carb, that port for the tube will need blocked off to use a left side shee carb on a blaster.
banshees also have dual TORS units, not regular carb caps.
they have to use TORS delete kits to get a regular cap and idle screw,
just like we do, but x 2
