Seems a very complicated way to go when all you need is an ignition system like the one electrex world sales http://www.electrexworld.co.uk/cgi-...D=xs650&PN=STK-465.html#aSTK_2d465#aSTK_2d465 just put it on the end of the crank all the wires are supplied, very simple and reliable, I run one on mine at the moment, I'll be using one on my next build as well, you can not run lights with this system it's ignition only.
