What do I set the retard switches to on my Yamaha Roadstar ignition?

The retard mode does not become active on the D3K7-3 unless you modify the TPS wiring harness (instructions are in the install guide). The retard mode will only be used for those machines that are nitrous, turbocharged or supercharger equipped. Therefore, switch position is not relative, as no retard will be active under normal conditions.
