I just bought my 06 zx14 and read all the posts. Decided to take out the flies. First off I have to say the whole job took me about 45min to 1hr. It went very easy and very smooth. I didnt use sny heat on the screwdriver, just a good snap on screwdriver and a small hammer to tap and break the loctite. Every screw came right out.
Now for the difference. I notice no hesitation, surging, anything. Runs as smooth as it did before, but hits incredibly hard at 3k rpm vs 7500 rpm. HUGE difference in low end torque. THIS IS how it should be. I haven't added the power commander yet and it runs flawless at light throttle, half, or full. I am very happy with this mod and would recomment it to anybody! and it was free!!!
Next will be the pipe and power commander.
Thanks evrybody
