Kurlon said:If your bike is jetted properly, and your current coil isn't faulty, a coil swap won't make a bit of difference. A higher output coil can sometimes mask and work around mild mis-jetting, but don't count on it.
Kurlon said:You can actually degrade performance with too hot a spark. : )
You only need the spark to be hot enough to initiate a flame front, any more than that is extra strain for no gain. I have yet to hear of anyone hitting combustion pressures high enough that even a stock chinese coil can't generate a viable spark.

turboglenn said:exactly.. i work in the performace car world and i get so sick of seeing people spend tons of money on aftermarket coils and ignition boxes on a car that's only making 215 horses... most of the time i just look at them and shake my head... then i show them how my car puts down 450+ HP on a stock ignition system... you only need more spark if you're generating enough cylinder pressure to "drown out" what the stock coil can produce. And most of the time it's the wires not transfering enough of the energy from the coil to the plug, not the coil lacking in power.
