Idle Cable?
I want to take the idle cable off my '01 1200C. Can it just come straight off without having to do anything else to the carb?

I beleive you can just take it off. The only thing is that your throttle will not snap back to idle when you let go of it - you'll have to roll it back to idle by hand.
Others will chime in that know for sure.

The answer is yes. You don't need it. I threw mine over board years ago.

OK, so the only purpose of the idle cable is to snap the throttle back to idle? So without the idle cable, do you have to "roll off" the throttle between shifts? Doesn't sound like much extra effort. |

No. You're misunderstanding the purpose of the idle cable. A spring on the throttle plate shaft snaps the throttle back to idle.
The idle cable is a safety devise that allows you to force the throttle to close in case the throttle gets stuck open. It was mandated by big brother. If your throttle never gets stuck it never does anything. |

Yup, safety device to ensure you can shut the throttle should the small spring in the TB/carb snap. Do you need the idle cable for the bike to run? Nope. Would I remove it? Nope.

Damn that big brother - putting warning labels all over everything and idle cables on motorcycles!  So the spring at the end of the idle cable sort of does the job of returning the engine to idle should the spring on the throttle plate shaft snap? Like a back-up spring so to speak?
It's coming off. |

No not really. When the idle cable is adjusted properly it has a lot of slop in it. It really doesn't have anything to do with the idle. It's just a cable that allows you to force the throttle to close if for some reason it gets stuck open. That's it's only function.
In the event that ever happened you could always just hit the kill button. |

I've had bikes with one cable and I've had bikes with 2.
It SHOULD still snap back with only one cable.
The second cable is more of a safety feature in case the throttle gets stuck at the carb, as stated by biknut. |

More correctly they should have called it an emergency cable, but that would probably scare people.
My car doesn't have a idle cable. Someone call Obama.
