I bought one of those universal body plug kits from Advance Auto a while back. One of the plugs in the kit fit the small PAIR hole inside the air box perfectly. Another choice is to go to your local craft store and buy set of the small tapered corks used for test tubes, etc. I was going to use one of these until I found the rubber plug that fit. After installation, my bike runs fantastic and not one once of popping from the exhaust on decal. I would recommend this modification to anybody out there running an aftermarket exhaust system. I used to own a 2011 Triumph Bonneville and one of the more common mods on those bikes was to block off the air injection system.
