yes thanks.
I've done loads of head sratching and research the biggest break through came when I found this system broken down and explained by a lawn mower manufacturer, in fact I've copied the signal conditioning stage from their system as the yamaha one is liable to cause the ignition timing to run off if it fails.
As you can see I've built my prototype version, on stripboard. I'm testing it this afternoon.
I've made it on long leads as I want the board 'off bike' as I'm borrowing my mate's osciloscope to see what's going on 'inside' when its running. My main corncern is the voltages off the capacitor, tuned circuits have a nasty habit of producing extremely high spike voltages, I'm using diodes rated at thousand volts and a cap rated at 630 volts - to be on the safe side with this build up! I also want to see the effect of various ideas I have also how much fiddling is possible with different signal conditioning stages.
have fun

). Ive got it to 18 degrees at idle advancing up to 36. That just rough estimates I took off the back of the timing light (I got one that you set at TDC and dial in the advance angle you want), I'll need to check that against soemthing a bit more accurate then a stick on dial.
