I can't remember where I came across it but 8000 volts on the spark plug side sticks in my head. Probably why the plug gap is so small. Dyna claims 30k volts and spark plug gap can go to .034". Huge difference in the numbers and in reality on the bike.
Yeah, 8K is pretty small for secondary voltage. Works though. I don't know what the voltage is, but I plan on putting some pretty good spark to it in the very near future.
I'm wanting something for a base reference figure and can't find anything. I haven't looked too deep into what the factory figures are but for what time I did spend looking I've come-up empty-handed. I did a search here and found nothing particular. I'll search a bit deeper this evening.
