Re: Charcoal canister removed?

Should you perhaps over fill out on the road; the overflow winds up back in either the hoses or the charcoal..........the engine will then not want to idle and will probably not want to play very nicely at higher speeds.............personally........and I do not have a clue how many miles you have on it .................if your careful and it's running...............don't get excited............if you should start to encounter those simptoms.............you know what to do...................

Re: Charcoal canister removed?

Living in Commifornia, you may want to hold off removing the cannister. There are new laws blowing in the wind that would require smog checks on motorcycles.

You could remove it, and just save it - just in case. I did remove mine years ago, but didn't save it!

Re: Charcoal canister removed?

Or, better yet, just disconnect the hose going from the tank to the canister and reroute toward the bottom of the bike. Put a bolt in the hose going from the canister to the fuel rail and just leave the canister where it is in case you need it later to get through emissions. Make sure the bolt is big enough to plug the hose or you will have a vacuum leak.

Do bypass or remove the canister though. I would gas up and the beastie would run like crap. Did a right side canister ligation and a left side canister reduction and it is smoooooooth as buttah. All the time!

Not just a problem with overfilling the tank. Mine clogged after baby decided to roll over and play dead.

Re: Charcoal canister removed?

I think the canister is sort of like the appendix - there but no one really knows why. I took mine out as soon as I found out about it on my 02 and have not noticed a difference, which is probably a good thing.

Never use a bolt or screw to plug a line and not expect a leak! Unless you get the tubing past any threads and onto a solid portion of the screw or bolt, there will be a considerable leak around the threads. If you want to plug any line without a leak, use a SOLID plug, easily available at almost any automotive parts store.

Re: Charcoal canister removed?

I would pull it out then reroute the tubes to dump overfill fuel down and on the ground. But save canister JIC.

Re: Charcoal canister removed?

On both my BMWs I still have the charcoal canisters installed as I haven't had any problems with either bike. On my Guzzi I removed it because it was messing with the idle when hot. Now the thing I noticed with the Guzzi which no longer has the canister and valve, is when the bike is hot and I park it in the garage there will be a strong smell of gas coming from the Guzzi. It usually isn't from any leaking gas but from the fumes in the tank expanding from the heat. When the bike is very hot with little fuel in the tank and parked, a clear liquid sometimes comes out one of the vent tubes. This liquid doesn't smell like gas but appears to be the ethanol in the fuel distilling out of the fuel when it's hot. I know it sounds strange but that's what it seems to be. One of these days I'll try and collect some of the fluid and see if it will burn.

I believe how the evaporative emission control system works is the canister which is full of charcoal, absorbs the gas fumes venting from the gas tank when the bike is parked and the valve in the system prevents any fumes from venting into the atmosphere. When the bike is running the valve opens allowing air to be drawn through the canister and any gas fumes stored in the charcoal are then sucked into the engine where they are burned.

Personally I wouldn't mess with removing the canister unless the bike was acting up because of it.

Re: Charcoal canister removed?

I just did the canisterectomy, but when I took the back cover off, I found the yellow cube flasher or relay looking thing out of it's socket and lying down in the wheel hump. All my turn signals are working. Before I plug it back in, what is it?

Your bike is likely a 99. I had the same on my 99LT and I removed it, instead of unplugging the temp sensor at the air box, to eliminate the engine hesitation in hot weather.
If your temp sensor is still plugged in then you can leave the yellow thingy off, otherwise plug it back in. Others prefer to leave it on and unplug the hear sensor. 6 of one or 1/2 dozen of the other...

Re: Charcoal canister removed?

It's a 2000 LT. Shoulda mentioned that.

I realized the answer to my question about 5 minutes after I posted, but thanks for your reply.
