Connecting the coil harness was only half the battle; reinstalling the fuel tank proved just as trying. Now I fully appreciate--and absolutely despise--Yoshii-sans significant mass centralization efforts. The CBR's mid-mounted fuel tank fills every last square millimeter behind the engine, over the transmission, and in front of the battery box. The tank hugs the airbox so closely I had to trim the thin sound matting to make room for the Z-Fi's added injector leads, and there wasn't even enough room beneath the tank for the main wire bundle, roughly the same diameter as a cheap cigar. After removing the (full!) tank and rearranging the wires a half-dozen times I finally gave up, put my full weight on the tank to crush the harness into submission, and bolted the tank into place. The entire installation took four hours, including wiring the quickshifter and installing the bike-specific shift rod. Plan accordingly, or don't be surprised if your mechanic quotes a steep labor charge.
