No kickstart on the 650. You need to sit down and nail down what all you're gunna have wired up at the end of the project and do it all at once because it's a lot easier to make things neat and tidy when you aren't doing it piecemeal. If it's your first time wiring anything or playing with electricity I recommend you stick to the harness. But if you're feeling froggy, you can replace the expensive reg/rect with generic parts for much cheaper but you *need to know your stuff.* You could also do the cavalier coil mod, which is pretty sweet. But know what you're getting into. Youll have to draw your own diagrams, be smart about your grounds, distribute fuses accordingly, think about how you'll even mount and strap everything.... It's a lot of work to do it from scratch.
