That's straight forward. If you're basing it off the 3:1 dwell crank angle system.
My goal is to leave the coil uncharged for as long as possible to reduce heat and stop charge at full saturation. I think that's where a lot, if not all, the heat from the coil on my customers XS650 is coming from. I'd like to figure it out so that at idle it'll be just enough for the bike not to "break up" or "misfire".
Also I'm fairly sure that the reduced dwell time....angle will result in a much better engine performance on the XS at higher RPM's.
So far it looks like most, if not all, the coils sold for the XS that I've come across are under loaded than needed and actually sitting around getting full amps too long and heating them. Suspect this is done for better starting? IDK and I don't agree. I really think less duration will be key to a better performing more reliable ignition for my customer.
Getting back to this thread-
as you lower the battery voltage it'll increase the time it takes for the coil to charge and reduce the optimum RPM. If the battery is low enough or the "amps to the coil" it'll actually never saturate the coil entirely. "dead battery won't start a DC ignition"
Clearly than you can see how grounds for the ignition system can affect the "spark" performance of the bike.
