I'm sorry but I'm new. This is my first bike and I don't know very much about anything. I have a 09' XB City X. I've been looking everywhere and nobody else's bike has one. What does it do?  | ||

It is for CA emissions. Charcoal canister, I believe. | ||

george pegged it. ca emissions charcoal canister. | ||

Wait 'til you see what Cali bikes will get to capture the killer CO2! | ||

It makes the bike look like crap, that's what it does. I would move. | ||

welcome to badweb, fellow californian! it captures/scrubs the vented gasoline vapors. it can be removed, you just need to plug off the fitting on the throttle body. i will be doing mine soon. keep all the parts if you do, so the new owner (if you ever sell) will have the orig parts.

Can you make a splooge catch can out of it? | ||

does Harley-Davidson carry that part in Chrome ? | ||

The fuel tank on all vehicles need to be vented for a few reasons: 1) As fuel is used up, the vent allows air to flow into the tank to replace the volume of fuel used as your ride. 2) Fuel changes volume as it changes temperature. It expands with increasing temperature and contracts with decreasing temperature. The vent allows air to flow in on contraction and fuel vapors to flow out with expansion. There is portion of the tank which you cannot easily fill with fuel. This is the vapor space and is sized to prevent liquid fuel from spilling out of the vent at point of maximum fuel expansion. 3) Fuel has a relatively high vapor pressure just sitting there. The vent lets fuel vapor escape. All of the above are to keep the fuel tank from either collapsing in on itself, blowing up like a balloon due to in-tank pressure, or spilling fuel on the floor. California does not allow powersport vehicles to freely vent fuel out of it's fuel tanks. A portion of these vapors are captured by the charcoal filter in the carbon canister. Note that the canister is vented to atmosphere on one end and connected to the fuel tank and FI system on the other. The atmospheric side allows the fuel tank to "breath" but filters out much of the vapor prior to venting to atmosphere. When you turn on your bike, the purge valve on the canister is opened and the vapors trapped in charcoal are sucked into the motor, where they are burnt. California tests the entire motorcycle in a "shed", where it is let sit for some time and the evaporative emissions leaked into the shed are measured. The carbon canister is sized to keep the evaporative emissions below the threshold in this test. The test is known as a "shed test". Note that fuel vapors are not necessarily the only source of evaporative emissions. Emission from chemicals in the tires, chemicals in plastics, rubber hoses, etc., can also effect the results. The other 49 states do not require total vehicle shed tests (yet). Starting with the 2008 model year, only the fuel tanks of 49 state vehicles must meet a certain evaporative emission requirement. Thus only the fuel tanks of 49 state bikes are "shed tested". This is a false environmental benefit as those tanks are still vented to atmosphere. I suspect the EPA intends to require total vehicle "shed testing" at some point for all motorcycles sold in all states (much like cars) and is just softening the manufacturers up at this point. They like 5 year cycles, so maybe 2013 will be the year they up the ante. | ||

it rubs up against your left leg. thats all it does. | ||

I'd seal up the hose going to the purge valve (or plug the fittings on the throttle bodes) if I removed the canister and valve. | ||

California blows ass, they are the reason we don’t have fuel efficient diesel cars over here that get 70mpg and that’s just one of the many reasons that CA should earthquake itself over to Japan. |
