I just purchased a brand new 07 cbr1000rr over the summer. This is my first sport bike and my first winter with it. I would like to make the bikes down time productive by adding some performance mods. ( I live in Ohio the weather sucks this time of year). Im planning on putting on a hyper-flo slip on exhaust. I recently read about the "flapper mod" and plan on doing that over the winter. Does any one have any easy modification suggestions like the "flapper mod"? Any info will be greatly apprieciated. Thank you.
