Carbon/Charcoal canister for emissions.

You can remove it if you want. The line from your tank to the rollover valve then to the canister should be free to vent to the ground (keep the roll over valve inline). The line to your throttle body can be removed and cap the throttle body nipples.

You will notice a fuel smell around your bike on hot days though, will void your warranty, and wont pass emissions in California and likely other states/countries

Oh and you'll tick off the Greenies out there by contributing un necessary hydrocarbons into the environment ;)

Be sure to block off the bung at the throttle body and re-route tank vent hose should you pull it.

Im sure most know but the system works by bringing in fresh air via vacuum at the TB from the canister atmosphere vent and air is filtered through the carbon/charcoal and draws up with the fuel vapor trapped inside to be burned in combustion.

...So in other words, it's perfectly safe to remove. :)

I was going to ask the same question about that dumb EPA can. From the diagram under the passenger seat, it looks like we all have the "California" model (?). I mean really, a catalytic converter and an emissions canister on a 321cc engine?

My bike has been on a diet but cannot find this?
obviously not looking hard enough,


for racing here, i'll have to plumb it anyway (if its there)-
k) Engine and gearbox breather tubes and the radiator bottle overflow must exhaust into the air box to the rear of the intakes. The lower air box breather tubes must be blocked

You probably don't have one. California has strict emissions standards and most manufacturers don't bother importing different models here for the other 49 states, so all US bikes have the canister.

Is it safe to remove the canister and just leave the hoses hanging (ziptied)? Or do you have to use block off plates and cap the hose as has been explained here?
