Re: Twitchy bike
Oh yeah... Definitely worth it. Smooths out the bike and here's why: other than being a physically smaller tube, the f4i tube is round where the cable lays. The 07 and up 600rr has a slightly oblong shape. The reason why is: honda tried to electronically simulate a slipper clutch with a dynamic ignition map. When the engine brake increases at a given rate, the ecm tries to alter the engine brake with ignition timing and an electronic stepping motor in the throttlebody assembly. The throttle tube was designed as a quick turn throttle with a decreasing radius, so that the engine brake is more severe and the throttlebodies close more abruptly, enabling the ecm to sense the increased engine brake. Long story short, the f4i tube works. It will smooth the bike out. You have to remove the airbox and take up cable slack by the throttlebodies if you install one. Worth the 9.95 and the 15 minutes of work in my opinion.

Re: Twitchy bike
thanks for the insight btw
did it help when backing off to keep the throttle from slamming shut? its almost as if you move your wrist a fraction to get off the gas and the whole damn thing wants to drop.

Yes. It very specifically helps with that.
