Re: 2013 honda cbr1000rr
There is an airbox mod that one can do that removes the vacuum flaps. That will increase flow to the filter. The vacuum cans (and the flaps...) are removed, and the vacuum lines plugged. It can be "undone" if you sell the bike later. I would, if I were Ryota, be very careful and make sure that the "mod" does not affect the warranty. Many dealers are getting really picky when a bike is brought in for a warranty service and something has been done to the "emissions", injection, etc. As an example, I had to go to the dealer about a slip on and the servo disconnect (servo buddy) on my ZX6R. Their "position" was that as long as the FI light and ECU did not "register" a problem, then they would honor the warranty.
Don't anyone get me wrong here. Most dealers are"loyal" to their customers, particularly customers loyal to them, etc. But... I have "friends in high places" as in my 'son-in-law' is the Parts Manager for the local bike dealership. I personally know the owners, etc. They have "warranty horror stories" where a "customer" (usually a "squid") brings a bike back after running it with aftermarket parts, low oil, excessive rpm's, etc. Basically what I'm saying is make sure you are ok with the "service manager" when it comes to doing anything not in the owner's manual while the bike is under warranty...
