So I have a newish issue for my 2006 XB12X 27,000 miles. When cold it fires right up, then idle drops to 500 then 1000 then 500 and dies. Hit the button and fires right back up and will do the same thing. If I sit with it and throttle it and keep it running after it warms up for a few minutes it purrs like a kitten at 1000 rpm idle. Will not die at idle when warm. Only a cold start. Plugs were changed 7,000 miles ago along with air filter. It just kinda started doing this a few thousand miles ago. Any suggestions on what it might be??? Thanks. |

Grip your battery cables with your fingers, try real hard to turn them either way. If they move at all, tighten the battery cables. If not, make sure to charge the battery then test voltage. It should be around 12.5V, no load, fully charged. Test starting spike, should not go below 9.0V when cranking. Then check grounds. Then go to TPS reset. Make sure engine is warmed up when TPS is done. |

Voltage is not the issue, I have a volt meter hooked to the bike at all the times, it is hard wired in on my dash. Even when it dies on cold start it runs 13.5 to 14.0 volts. I checked TPS with the ECM Spy, it looked good. Cables are tight on battery. ???I was thinking TPS but it runs fine when warm? Would the TPS change from cold engine to warm. |

Bad temp sensor? Sensor always indicating warm engine, so FI does not enrichen fuel mixture while bike is cold and bike won't idle. When engine comes up to temp FI is already providing the correct mixture so it idles fine. |

Mine was doing the exact same thing. A TPS reset did the trick. |

I will try another Tps since I have the cable and ECM spy. The temp sensor is that the one in the airbox between the breathers? |

There is also a temp sensor on the rear cylinder head, but I think the one in the airbox would be the one that could be affecting this. I imagine you can check it in ECMspy. |

The one between the breathers is the air intake sensor. It could also cause the same thing. |

Check the IAC sensor inside the airbox. Make sure its not covered in gunk and functioning properly. |

I will check that sensor. I do keep my oil on the full side. Could I spray the sensor with a little carb cleaner or would that kill it for sure? |
