I used this kit for a couple of weeks before I put my bike back stock and sold it yesterday. It is for a ZZR1200 but the needles are the same as the ZX11D kit.Needle ID # is 0942i-56v_ti. Kit # is CRB-K57-1.1-Ti. It is complete with the springs and allen float bowl screws. There are 5 sizes of MJ for the ZZR1200 which are smaller than ZX11 MJ's so I included 4 160's, 4 165's and 2 162's. All washers and e-clips are included as well. I was more impressed by how much smoother the bike was than the performance. If you use this kit you MUST I repeat MUST set float height to 15mm or you will have full throttle low rpm stumbling. First 55 bucks gets it shipped in the US.
