I too believe that you have the later style carb with the now common 5 inch throat size. You can do what I did... simply go to the auto parts store and buy a 10 inch chrome air cleaner assembly, one of the cheap ones at about $15.00. Just use the base with your cover and the corresponding air filter. I used the K&N filter correct for the Commando air cleaner assembly. It works for me!!! Geof
