My 2003 NT goes thru:
Phase 1 - At approximately 320˚ F the ECM will gradually reduce engine idle speed until the engine temperature drops or the engine reaches 800 rpm.
Phase 2 - If engine temperature reaches 338˚ F the ECM richens the air/fuel ratio to provide additional cooling.
Phase 3 - If the engine temperature reaches 356˚ F fuel injector pulses are interrupted. The air drawn in and expelled helps cool the engine further. Since there is no combustion it would be perceived as a misfire. This third stage will only happen when the motorcycle is stationary.
Phase 2 - If engine temperature reaches 338˚ F the ECM richens the air/fuel ratio to provide additional cooling.
Phase 3 - If the engine temperature reaches 356˚ F fuel injector pulses are interrupted. The air drawn in and expelled helps cool the engine further. Since there is no combustion it would be perceived as a misfire. This third stage will only happen when the motorcycle is stationary.
