I posted a link on how to fix the buzz on the zx10 in another thread but that is for the 04 & 05's. For the 06 its alot simpler. 2 rattles but my bike only has one of them. Theres a rattle in the keyhole for the ignition which is fixed by putting a small piece of rubber vacuum line over the key to keep pressure on things (I will post pic of my key when I can). The other is the gascap and I dont have this problem or a solution for yet.
