I’ve also checked the other option, the 123 Ignition dizzy. They require coils with a minimum resistance of 1 ohm, so they should be able to handle the 1.5-ohm coil.
I have no idea why the CSI can only handle coils with a resistance of 3 ohms.
However, Swiftune sells these CSI dizzys and claims that they provide more power and lower emissions.
