and have question, on most bikes they just plug airbox hose and route the tank hose down along with the other drain hoses, but on some they plug both evap hoses, and unplug one of the drain hoses which is down there already blocked allowing tank to breath. How is with the v-strom?

Probably not necessary to remove Evap on Gen2 (2012) and later unless its causing a problem which seems unlikely on a new bike and should be fixed under warranty if it is.

On earlier bikes the only problem it would (rarely) cause is if the charcoal cannister got saturated with fuel then the motor could be hard to start due to overly rich air/fuel mixture. On 2012 and later bikes Suzuki added an ECU controlled "wastegate" valve (see the throttle-body fiche for your bike) that blocks evap flow until the motor is running and the bike is at speed to prevent hard starting.

If you still want to remove it you'll have to find a "cannister delete" diagram online and compare that to the specific hose routing on your bike to figure out what to plug, remove or bypass, etc. There should be a sticker on the storage box under the seat of the hose routing. It is complicated but can be done.

thanks, but - firstly I need space under the seat and secondly I read and have seen charcoal can get back to the fuel filter and clog it. Good enough reason for me to remove it.

Maybe the Gen3 is different but on the Gen2 and Gen1 'Stroms the cannister is behind the side panels not under the seat. That is the only thing that really takes up any space, the rest of the system is just hoses snaking around under the tank/airbox/throttlebody.

...secondly I read and have seen charcoal can get back to the fuel filter and clog it. Good enough reason for me to remove it.
That is not even possible on the 'Strom, maybe that could happen on some other (older?) bikes but I am skeptical even of that. The EVAP (evaporative emission control) system is for processing fuel vapors not liquid fuel and does not involve the fuel filter whatsoever.

NB: If you do remove it save the parts, some states are inspecting emissions on registration or title transfer.

Of all the bikes I've had with the canister none has clogged the can with fuel and I fill to the brim each fill-up. How folks had problems is a mystery.
In the grand scheme of things, charcoal canisters are supposed to help clean up the residuals of a gas engine operating.
Removing items that help us breath less polluted air is counter productive.
This is a reminder from your conscience to not F with things! :fineprint:

Hopefully you will get a post that gives detailed instruction to accomplish your task.
Doncha just hate posts that suggest you shouldn't tun with scissors?>:)

BTW cannot believe nobody did it yet on v-strom, there are plenty of examples on tube about evap delete on bmw or ktm bikes.
For many rider removing SAS, EVAP are the very first mods what they do.

Probably because its not really necessary ('Strommers are a practical bunch). I don't really care if you remove it but unfortunately you'll have to figure it out for yourself because it's not common. If you do it you could post your findings here for anyone who wants to follow your lead, this is how forums work. Be the change you want to see. Racers remove the EVAP but mainly for weight savings so look for EVAP/cannister delete for an SV (same as the DL motor) or at least a GSX-R (same brand) which are commonly raced and will have a EVAP system similar to the 'Strom. Compare the diagram with the sticker under your seat to figure out how it works and what to plug, cut, remove.

BTW, there is a history to why people remove emissions components (EVAP, PAIR, EGR, PCV, timing limits, etc). Way back in the '80 and 90's when emissions laws were put in place the car and motorcycle manufactures didn't redesign the motors they just slapped on poorly designed junk to meet the standards. This made cars and bikes run poorly and have driveability issues and people quickly learned that removing the junk made things better. EPA's counter move was to slap huge fines (+$10,000) for messing with emission systems. Those laws are still on the books (with exceptions for racing). Fast forward 20+ years and engines have all been redesigned with emission systems integrated into the motor so they don't really cause any problems unless there is something wrong. Unfortunately, many people are stuck in the '90's and think there are benefits to removing emissions components but now removing them can cause motors to run poorly and have driveability issues so the situation has flipped. (I am ignoring the impact on the air quality which is a separate issue).

To be fair, running with scissors may cause harm to the runner alone. Dumping fuel vapors into the atmosphere effects everybody. If we all rationalized that our little contribution to air pollution won't make a difference, then we'd all be fooling ourselves. That's exactly how it works. Millions of individual vehicles each making a small contribution.

oh gush, what we have here. I bet you believe also in global warming and Santa Claus...

forget it, will find on other forum or figure it out by myself.

Uh, oh, Maybe we lost a potential contributor to the collective knowledge.
Wonder what the guys on the ADV site have to suggest about canisterectomys?
I do remember it being a hot topic on some sites.

Oh, so THAT'S what they're for

I removed my seat to see why the O.P.wanted more room under there. Seems pretty cavernous, IMO. I have a 49-state version with no evaporations canister, and I always wondered why there were two molded-in tabs sticking up on the base behind the tool caddy. They didn't seem to serve any purpose. I even looked on Suzuki's website to see if there was some kind of document holder or first aid kit or something that installed on these two tabs. Finding nothing, I ground them off, as they were in the way of the documents, disc lock and tire plug kit I like to carry under the seat.
It wan't until reading this thread that I looked in my service manual under the section dealing with evap removal that I found out the tabs were there to hold the canister.

I have no problem removing evap systems on my motorcycles and all of them have had it done to them.

The 8 drops of gas that might drip onto the ground while refueling my motorcycle in pales in comparison to the 40 to 60 gallons of gasoline I burn going to and from work.
