As well as the can mod   last week I also did the air box flapper mod ,
A "Seat of the pants" feeling is the mid range is a bit stronger .

Hi All, I'm fairly new to the CBF but have covered some decent miles on it. I agree it's too quiet so going to try this mod out this weekend. What is the air box flapper mod?

As I understand it ,
In the Air box is a vacuum operated flapper that closes at certain revs to reduce intake  noise for testing .
removing the pipe and blocking it up prevents the valve from closing increasing air flow throughout the range.
Might be tosh but it seems to work for me :mfrlol:
