There are two pipes going into the canister. One is a fuel vent that goes from the frame. Where does the other tube come from? |

left side of front throttle body... I actually plugged mine at that site and rerouted to the inside of my air box via a hole i made in the bottom..... about 15,000 miles ago |

Tbowdre, So you plugged the nipple on throttle body and ran the hose to your air box? |

OK, I give up..........why? Your perceived improvement is what? |

They don't plug up Danny. The purpose is only fuel vapor control. You know, the green thing. The system has no effect on performance, working or not. |

Actually it has a huge effect on performance, the bike will not start at operating temperature in hot ambient temps with the charcoal canister routed to the throttle body, just creates a way too rich condition, short stop to gas up for example, I route mine through the canister to ground, problem solved and no gas fumes, even a Ferrari, if it will not start, is a crap performer. |

I rerouted mine because (1) I have "mental problems" and (2) I didn't like the variable about of fuel vapor to be pulled into one of the throttle bodies. So MY perceived benefit is I still have a bit of a vacuum to the canister and any additional fuel vapor is going into both throttle bodies. whatever ![: )](http://www.badweatherbikers.com/buell/clipart/happy.gif) |

I still don't get this... my friend has a Cali bike and i don't. Therefore I don't have the extra tube and he does. He wants to get rid of the extra tube on his bike since he has an xb tail and there is no room for a canister. So what does the non-cali bikes do differently since they don't have this extra tube? |

In the beginning I overfilled my gas tank and thermal expansion caused a stinky garage situation. I had the dealer put on the cali can. In an overfilled gas tank thermal expansion will push gasoline over to the cali charcoal canister. Apparently a plugged canister can cause some sort of vapor lock, the gas tank has to breathe to flow properly. I plugged the carb vacuum line and plumbed the tank's vent line to the NON cali original location behind the left rear foot peg. I just don't overfill the tank, problem solved. |

Andros, if you do remove the charcoal canister and want to sell it, please let me know. I have been looking for one for a while. Thanks. |

The non-CA bikes have the vacuum port on the throttle body capped and the vent tube from the fuel tank routed to the atmosphere, venting near the passenger foot peg. The problem with this is that the bike often drips a puddle of fuel on the ground and even if it's not dripping it creates a very strong fuel odor. As noted, CA bikes have a charcoal canister that is charged by the fuel tank overflow and is evacuated by the throttle body vacuum port. In normal operation the O2 sensor instructs the fuel injection to compensate for the additional fuel coming from the canister. The problem with this is when the bike is hot and refueled to it's maximum level, excess fuel percolates into the canister and saturates the charcoal. This can cause a momentary over rich situation which, in my experience, is quickly resolved in a few seconds. The symptoms are very, rough running sometimes only on one cylinder. This problem can be completely avoided by careful filling of the fuel tank to somewhat less than maximum. Some have suggested an alternative resolution of capping the vacuum port on the throttle body and routing the vacuum line into the air box. This makes no sense. The air box is often in a pressurized state and likely will never achieve sufficient vacuum to evacuate the canister which renders the canister useless and potentially clogged thus inhibiting proper fuel tank venting. |

Thinking outloud. But what if you skipped the canister and just vented the tank to the airbox? |

Thanks all. Fuel dripping is no problem. All i want is to get rid of the throttlebody pipe. Ill cap it then. Cool. Im in denmark so sending the canister over will probably be too expensive to be feasible. |

This is the best way to handle vapors.
