We are coming to the final stages of our build with the Duc and we just finished installing the airbox and throttle body bracket.
Here are some pictures of the ordeal :P

^ Here is the beginning, tank off and ready to start taring it apart.

^ Here is the airbox removed, now we begin taking the throttles of the stock airbox and remove the steel bracket.

^ Here is the carbon fiber bracket that will be replacing the steel one that holds the throttle bodies to the airbox.
The stock bracket was 341.1grams, the carbon fiber one is 150.6 grams. 44% weight savings there.

^ Re-installing the throttle bodies to the new carbon fiber bracket.

^ Here is the bracket bolted onto the carbon airbox.
The stock airbox is 3lbs the carbon fiber is 1.25lbs that's 58% lighter than the stock airbox.

^ Pondering what to do next :P
