I thought that replacing the standard CDI would help some but not this much! I perfected my design and got almost 10% power gain. I used to climb one street at 20.5mph but now I do so at 22.5mph. That's a gain of 9.75%. But there's science to back up this idea. (see "Devices to improve the performance of a conventional two-stroke spark ignition engine") Since 2.5% more power is derived from each 33% increase in spark power then a 10% increase of power means the new CDI has 133% more spark power! Not so amazing really considering how small the ignition coil must be to fit inside the standard CDI/coil combo. To read more about this all go to my page about Ignition Timing Changes
The CDI is now available for purchase also.
