yea, angus is right.It just pulls off and is right next to the tank under the seat. Some say it's for intake noise reduction. But while it does reduce intake noise on the booneville quite a lot according to bonnie owners, it make almost no nise difference on the america and speedy.What it DEFINATLY does do is linit the amount of air intake and pulling it off has been proven to show at least 2 HP increase. When i pulled mine i was quite suprised at the boost i got and even more after i shimmed the needles which the extra intake allows.
