    I have a 2003 VFR800. There was at some time a fabled writeup on removing the Evap Canister, but it has disappeared.

    Can someone guide me on what I should do?

    There is two lines that goto the evap canister. One is a vent hose from the tank. I assume I can just remove this hose completely and let the tank just vent to the open air? Or do I need to leave the hose on it?

    The other is a connection to the air box, which I assume I can just plug.

    Can I remove the eval canister? Some people have said some sort of fairing bracket is involved in the eval canister, anyone know? I would love to just elimate it so to make oil changes easier and clean things up.

    Also there is a air bypass solenoid, can I remove this or will it throw a fault? If it will throw a fault I can just leave it connected and tape it up.

    Super thanks!

    I removed mine, the canister and I think it does leave a hole in the fairing where a bolt used to go, I believe I unplugged my solenoid...

    Can someone be more clear on the evap removal, here is my understanding:

    One hose goes from the tank to the canister, this is a vent hose. You can unplug this from the canister and run it out the bottom of the bike or wherever you wish, just make sure its dressed nice and doesn't kink.

    The other connection on the right side is the air coming from the canister to the intake. You can remove the vacuum lines, vacuum line 5-way connector, solenoid, and just make sure you cap off all air intake ports you remove vacuum lines from with vacuum caps.

    Does this sound correct?

    You have it correct.

    BUT, do not, repeat, do not point it in a manner that will conduct fuel vapor anywhere near your exhaust header. This includes out in front of the engine where the big heavy old evap can used to sit. IF you should get some overflow blow out that lil tube, like I said, the factory dump tube bracket throws it away from both the back tire, and the header.

    Voided76, thanks that makes a lot of sense. The factory evap I think has a hose on the left that takes any spill and sends it out the bottom of the bike with the other 3 hoses for drainage. My plan is to route it there so it looks all "original". I think thats how the manual shows it goes for non-US bikes where they don't have a evap canister.
