evap can removal for CA models

it's pretty straightforward, just involves capping (or not) a nipple in the front of the airbox, and hooking the 2 vent lines coming out the side of the tank (the red dot and blue dot lines) together with a piece of U-shaped tubing, and you're done. the red and blue together allow the tank to vent thru the cap. the other alternative is to connect all 3 lines together and the vents are now hooked up to the overflow. that's the way it's been on my triumph for years and never a prob.

Why would you even bother to do this? All the evap system does is store the vapors from the fuel tank, until they can be sucked into the engine, and burned up during startup. It does nothing to restrict performance. Also, the gas cap is sealed and it will not vent through the cap. It is designed to vent through the evap system. It means you won't smell gas fumes in your garage, and the fumes will not end up in the atmosphere. Understand what something does, and understand it is illegal to tamper with it, in fact it is a felony!

Hey, landlord, I never said I did it, I just figured out HOW to do it. It's academic, so chill out. It doesn't seem that the gas cap is sealed, either. blow thru the hoses and you'll see.

Landlord -
No disrespect intended, but the problem with the CA evap canisters is not so much performance, more aesthetics, and no hard data that shows that they do any good. California riders get saddled with this obnoxious, ugly afterthought that gets in the way, and which practically doesn't do a whole helluva lot to keep the emissions clean. The best it does is keep a tiny fraction of gasoline vapors from venting to the outside. It's not like these bikes are losing gallons of gasoline to evaporation anyway -- the tank is still mostly a closed system, otherwise our fuel efficiency would be crap. And this bike, and many others like it, have actually met strict European emissions requirements. If any of the bikes not sold with evap canisters was seriously venting gasoline into the atmosphere, you would have seen many garages that would have blown up by now.

Also, I seriously doubt that it's a felony to tamper with it. I know of exactly zero bikes that get emissions tested in California after they're sold, and all of our licensing and restrictions do very little to keep 49 state bikes out of CA anyway. Ask the guys riding red Versys in CA ...

It wouldn't bother me so much if a) the canister was discreet, unobtrusive, and a normal design element of the bike, and b) if the California Air Resources Board (CARB) flexed its regulatory might toward far worse polluters in our state, including thousands of seriously polluting vehicles that cross at our border with Mexico each and every day. Cars and trucks that not only have completely inadequate emissions controls, some which are blatant smokers, and some that pose a very real and dangerous hazard just being on the road. If you've driven anywhere on the freeways from San Diego to LA, you've seen what I'm talking about.

Instead what we have are manufacturers that have to build a whole different tank and hose routing setup on a motorcycle that represents a tiny portion of the total motoring public, and which realistically can't account for even a remotely significant portion of the air pollution when 95% of the drivers are in cars. These restrictions limit the public's access to motorcycle models that are freely available elsewhere. In California, which must represent a significant portion of the motorcycle buying population of the USA due to our generally mild weather all year throughout the state, we're limited in what models we can buy because bikes that meet all other states and countries' requirements, don't pass the muster with CARB. Which is why it took two years for California to get the Versys.

So if a motorcycle owner wants to remove the evap canister of a motorcycle he/she owns, far be it for me to find fault with that. No worse than straight pipes on Harley's or removing baffles on sport bike pipes, and less annoying to the public at large.

Well said, DarcyM....
and as an addendum, seems like connecting the 2 hoses together should work, and does, but the when the cap is opened, there's a whoosh, so connecting all 3 together seems to be the way to go, academically, of course.

Issues with Leaving the Evap Canister on

4 points:

1. T ing all 3 lines together will work well because the cap does have a vent. Normally that vent is through the charcoal Canister.
2. If you overfill the tank with the Canister installed the manual say that you need to replace the canister because it is ruined!
3. If the canister is ruined/plugged with wet fuel the tank will have venting problems and can stall.
4. When the Bike is dropped fuel will get into the canister and the bike may not run without work or may run poorly until the slow flow or vented air through the canister "dries out" the canister.

+1 on darcym's post. When I get a Versys, evap is the first thing I'd do. I already did it to my current ride - took 10 minutes.

Yeah, that’s a statistic sample size of 1, category “anecdotal evidence”, but there it is.

My plan is to remove the canister but leave the vacuum switch connected. I will bypass the canister hoses which will allow the tank to vent with and without vacuum as intended. I will remount the switch and hoses in an obscure location.

Any comments or suggestions?

We did this on my sons 250 and the garage always smelled like gas so we put it back on . Makes no sense to remove it anyway.

For all the people that say don't remove it.......If it's such a good thing to have on the bike WHY doesn't every Versys have one? I removed mine pretty early on and never looked back. I never had a smell of gas, and got almost 1/2 gallon MORE fuel capacity!! WIN WIN
These are the directions I followed:

Just a quick clarification for those of you with a newer versys with different color coding on the fittings...

On the tank:
Blue is fuel vent/drain. Run a hose down the bike incase anything comes out. It will keep gas away from the bike.

Black/no color is a return- cap this.

Cap the vacuum fitting on the throttle body which had previously run to the canister.

The green hose can either be sealed with a bolt, vacuum fitting and rubber cap, or you can trace it up and cap it at the source. This will require removing the air box, which I'm pretty sure it is connected to.

What's with the Cali hating? I get that you don't favor unnecessary emission add-ons like the useless evap canister - which I made quick work of removing soon after I got my '13 V home - but no need to get all hostile about it.

I removed the one on my '09 soon after getting it; my '08 doesn't have one; and my '15 doesn't either, altho' it DOES have something.... There are some lines attached to the tank, IF I remember correctly.

Sorry not meaning to bash Calif people I love the people and the state itself it's the ridiculous regulations California has that drive me away. I have friends who struggle with their small business (ranchers, mechanics) because of increasing ridiculous rules. So when I find a California tumor on my bike I am compelled to remove it!
