As far as the installation process, just follow #165 on 650motorcycles.com. The only place I got stuck was that final connection for power and it turned out to be as simple as plugging in the red wire from the box to the new coil, cutting it in the middle and connecting it to the hot wire (red with white tracer) that went to the old left coil. The other hot from the right coil and the two other old coil connections go unused (capped and taped). The only variation I had from the article is my factory coil mounts are different than the one in article #165. His are square while mine have a butterfly shape and basically nowhere to drill a second hole for the new coil so I had to fab my own little adapter mount out of aluminum strap. The timing was simple, roll the motor over to the first mark and set the magnets behind the staor so the white dot is showing. The stater plate has slotted mounting holes so if you mount it in the middle of the slots, you have a few degrees either way to adjust. When I first finished up, I kicked her a couple times and could tell the timing was off. I loosed up the stator and tweaked it a couple degrees and she came back to life. No timing light involved and she is running dead on. As others have said, the bike runs alot smoother and the engine noise while riding is a little quieter. Overall it's like a different bike. It's odd to be able to ride and not have to compensate for an anticipated dead spot or worrying if the advance is gonna stick at the next red light. If not for my second guessing the final connection, it was probably an hour and a half install tops, although I soldered up the new ignition wires the night before in preperation. If you have any specific questions let me know.......I'll trade advice for that allow tank you have........lucky bastard j/k!!! Basically the bike is running great and I no longer wish to douse it with gas and touch a road flare to it.....
