^^I second yb^^ A 'shee carburetor has the same bore size (26mm) as the stock one on a Blasty, so putting a Banshee carb. on a Blaster won't yield a performance improvement. Also, be warned that the stock RH side carburetor from a Banshee is not equipped with an enrichener ('choke') valve, so you must use a LH side Banshee carb. to replace the stocker on a Blasty in order to have a properly-functioning choke.
