This is some pics of the air box mod that I worked on this morning at 3 am because I became board. Man I hate when that happens! Anyway I did the usually drilling and hacking like the brock website describes and I desided to eliminate the valve on the bottom side of the box. I used a piece of the flapper valve that I remove since it is the same material as the box and melted it to the box using my hot air plastic welder from harbor freight ($29)! Or you can use a soldering iron. It was easy and eliminated a very small amount of weight. Just thought I would post for others to maybe consider. Now off to bed, tired. Any questions just ask.
USMCbusa, from what I have read the air box mod is for people that have modified their bikes from stock. Meaning they have a full aftermarket exhaust systems (not slipons) usually 4-2-1 set-ups, k&n or bmc air filters, TRE, and of coarse power comanders. Basically you open up the airway that feeds this beast of a motor. Take out your air filter and see how small the rectangular hole is that the intake is. You will see that there is a triangular shaped area, where the rectangular hole is glue or welded in. This is what comes out. In conclusion, you are going to double the size of the air opening that feeds your busa. This results in more "potential for power" if you have the right amount of fuel to use it. I will let you guys know when I test to give my opinion, raining outside 100%
