"Everyone likes freebies right? Especially in the power delivery department. In a time where horsepower typically cost $100 US per, it's nice to find ways to add ponies for free. The flapper modification is one of the easiest and most cost effective modifications that can be made to the CBR 1000RR. There is a plastic "flapper" door mounted in the front of the intake. The flap only operates with the bike in gear, load on the motor, and the clutch engaged (i.e. as if you were riding). You can not see the flap open and close with the bike up on a stand. If you look at the front of the bike just behind the front forks this flap is visible behind a small screen above the radiator. The flap remains shut at lower RPMs and is yet another emissions device that Honda put in place to meet noise limitations. This flap opens above 5,600 RPMs similar to the exhaust valve. The problem is that while this flap is closed the motor is forced to breath through two small openings on either side of the flap robbing the motor of low end power.
Disabling this flapper is very simple. You simply pull the vacuum hose off the gold flapper diaphragm valve and plug the vacuum hose with a suitable object such as a finely threaded screw. You don't have to remove any fairings to complete this, but I did to give me more access and allow me to secure the vacuum hose to the electrical wiring behind the fuse box. The hose is visible from the left side of the bike through the upper opening in the fairing. If your hand is small enough simply reach in and pull it from the diaphragm valve, just be careful to wriggle it loose so as not to dislodge the diaphragm valve. Once you have the vacuum hose plugged, secure the object in the hose with a zip tie, then zip tie the hose securely and safely out of the way of hot engine parts. You can also unplug the electrical connection from the solenoid to accomplish this modification, but I feel the vacuum tube method is the better way to go as you don't have to worry about water getting into any open electrical connections."
i dunno if that will help or not.. thats from a 05 1k respol
