Title: 696 charcoal canister removal
Post by: mrplease on May 23, 2009, 01:24:22 PM
i just got the ducati air deflector plastic part thingy that goes in place of the charcoal canister if you remove it. where it make it look the same as the other side of the bike. i'm trying to decide if i want to remove the canister or not.

can someone tell me what all i need to do to remove the canister? is it an easy job? also if i don't like the look is it gonna be hard to reinstall it?

Very easy. Just yank it all off and slap a couple vacuum caps on the metal nipples. You can even leave it attached to the old left shroud.

Edit: Use bolts! Mine were beginning to crack as well.
I was told by a local shop that I shouldn't use the vacuum caps for the throttle bodies because they get old and crack, then air can get through them. They gave me some bolts to use instead. When I took the vacuum caps off, they were already beginning to get some surface cracks, nothing too bad, but that was only after about 4 months.

well i would be installing a new left shroud and getting rid of the old shroud. so its as easy as just taking off the stuff, adding vacuum caps, and installing the new shroud?

how many caps will i need, where do i get them, and what size are they?

does anyone have a write up on how to remove the canister?

Can't help you with that one coz 696s in my part of the world are shipped without the thing.......  What purpose is it intended to serve??

Evaporitve Canister, it is filled with charcoal and it's job is to absorb gasoline fumes and burn them in the engine later.  A good idea, but they are ugly and cause problems when they old or you over fill your tank.  If you have a car, your car has one but you don't see it and it works better.

go to the how to section and i think there is a writeup.

to do it right, you need to get the euro parts pdf and take a look at how they run the tubing.

I personally simply removed the entire hose from the fuel tank; it's purpose has nothing to do with fuel pressure in the tank and everything to do with if you over fill, or spill some into the upper compartment between the filler and the cap. Remove the R/S plastic tank cover and pull the hose out. I ended up using an end cap off of my wire closet shelving to cover it and keep any excess fuel from spilling out in the future. (Note: If you leave this tube, do NOT plug it since it will simply enable all of the gas that gets in there to simply collect over time). Also, I left the throttle-body hose hanging under the engine itself. You can cap it, but it's not recommended. There is a perfect little nook on the L/S of the engine for this one to sit in without any fears of flames.


WOAH. that is allllll wrong. do not listen to that idea

the hoses to the throttle bodies are vacuum lines and without them sealed you'll have issues. also the hose he plugged on his tank is a pressure release line that vents fuel vapor, not overflow. you'll be building pressure in your fuel tank... not good.

that is the WRONG way to remove the canister.

the vent hose and the overflow hoses should be T'd together to let overflow and vapors out. also you should seal off the intake plenums.

WTF!..... again DO NOT DO THIS!!!

wow! thanks guys!

also, can i get some good pics of that side with the euro shroud. i have the part but i'm still on the fence if i want to do this mod or not. i am still thinking it looks better with the canister on. it makes that side look beefier and when removed it kind of looks like something is missing. not to mention the grooves looks easy to get dirty and a pain in the ass to clean. anyway i need pics from a few different angles. i'd appreciate it!!!!

Just look at the other side of your bike in a mirror. ;D

I never mind seeing more of the engine... or less plastic!

is there a way to take off the canister and install the new shroud, and if i don't like it install the charcoal canister back on? or is it a once its done, its done thing?

do i HAVE TO T the vent hose & overflow hose together? i am so confused. someone please help!

No. Just take all the hoses off entirely. Raux is talking some weirdness... :P (unless you top off regularly and plan on overfilling your tank)

(you can just leave them hanging somewhere if you prefer, but they definitely don't need to be joined)


Title: Re: 696 charcoal canister removal
Post by: mrplease on May 25, 2009, 08:03:03 PM
ok its done. simple really. just had to get it all figured out first.

only thing is i'm getting a strong gas smell. my friend suggested it wouldn't have the strong odor if we did T the vent hose and overflow together. is this correct?

That's weird reasoning—the fumes would just come out the end of the T instead of the red vent nipple. No fumes will come out of the overflow side unless there's gas trapped in the filler cap area (this would be visible). It's sealed when the filler cap is closed.

I just yanked both hoses. Risk of fire IF I over-fill and petrol drips down on a hot engine, but on top of the odds of that happening I'm not sure it would be easily accomplished while leaned over on the stand (black overflow nipple is also on the left side).

OK - So to add to the confusion here's my 2 cents worth:  I completely disagree with Holden and am in total agreement with how Raux has gone about removing this bloody thing. 

Why?  Coz "unless you top off regularly and plan on overfilling your tank" - One day you WILL overfill it.  Do you really want any  risk of fire, however remote?!?!?
Why?  Coz the way Raux describes having removed this thing is precisely the way my Aussie-delivered 696 was shipped from the factory. In other words Raux's method replicates the factory set-up for 696's in markets where the charcoal canister is not mandated.
Why?  Coz when it's really not that hard to do-it-like-the-factory-does-it, why the bloody hell wouldn't ya??

Post by: mrplease on May 26, 2009, 10:25:05 AM
ok here is what i did.

i removed the two hoses from the intake manifold. i plugged up the holes with some rubber nipples and clamped them on. that is basically all i did. so please tell me if this is what i need to do next... T the vent hose & the over flow hose together. and then i am hoping that is all i am suppose to do and i am also hoping i did it correct!


Title: Re: 696 charcoal canister removal

ANYONE?!?


Title: Re: 696 charcoal canister removal
Post by: Holden on May 26, 2009, 12:53:08 PM
IIRC the overflow hose is already routed straight down through the plastic hose guard (which I also removed). You just need to stick the vent hose somewhere it won't flop around. Again, no point in a T joint as the overflow hose is sealed when the gas cap is closed. Even if it weren't, what were you planning to achieve through that? Ah, I get it. That way the vent hose isn't "loose." That's optimal if you're going to keep the hose(s). Sorry for [being confused].

P.S. I am sure if your pump does not stop when it should there is going to be much more gas spilling out than the miniature overflow nipple is able to deal with. A U.S. gas pump delivers gas at a rate of 10 gallons per minute (1/6 gallon a second). Will gravity abate that current quickly enough through the pinhole?


Title: Re: 696 charcoal canister removal
Post by: Raux on May 26, 2009, 02:25:50 PM
sorry to take so long to reply.

the vent hose should be connected to the overfill hose to vent the fumes below the bike. the hose length kinda leaves it near a hot part of the engine. probably not a good thing. also, if you just take the hose off, you're venting fumes into the space in the tank panels where the battery resides also probably not a good thing.

awsome!

yeah thats what i'm planning on doing tonight. t connecting the vent hose to the overfill hose.

thanks for all the help guys!!!

Speaking from experience I did the canister removal, vacuum caps, t-fitting for vent and overflow hose and euro air conveyor. I can say with certainty (sadly) that the overflow hose cannot handle actually overflowing at the gas pump. Looks better without canister and runs smoother IMO without. It seems the canister set up a not so airtight situation. You'll be happy with this mod for sure.

Good point! Sure enough... starting to get grody...

Found a couple bolts in the garage.

I can say with certainty (sadly) that the overflow hose cannot handle actually overflowing at the gas pump.

This is not it's primary function.  The overflow hose is not there to channel away excess fuel if you're in an overflow situation at the pump, clearly the gas pump can dispense fuel faster than a tiny hose is gonna allow it to escape.  In that case you're in $hit  :(. 

The overflow hose is there to handle overflow due to fuel expansion. So for example.... if you  - even carefully without spilling - filled your tank to the very top and then.... left your bike parked in the sun, the fuel would expand and since you've left no ullage volume available (coz of your just-filled-it-all-the-way activity) the overflow hose allows the expanding fuel to escape.  I have actually done this, and I can tell ya that quite a constant dribble of fuel runs outa there and (more or less safely) onto the ground beneath the bike.  Imagine the outcome if you didnt have the overflow hose attached, where would the expanding fuel end up then??

i'll see if i can get a mess of them in germany when i get back. in fact i'll go to the DUcati dealer and double check the length and try to match them perfectly.

It must have come out of the vent side, as the filler cap seals airtight. The only way the overflow hose can function is if the filler cap is left open (or bursts open, in which case petrol will spray everywhere anyway). ???

Regardless, it may still be a valid reason to keep the vent (red nipple) hose on. Out of curiosity—how cool can metal be and still ignite petrol?

I've just been going through this thread.  I think I have an idea of everything I need - Just:

M6x8 (or M6x10)
Y Adapter

2 Questions:
What size on the Y adapter?
Did I miss anything?

actually the hoses are different diameters. you may need an adapter. i bought a small kit with a bunch of y adapters and diameter adapters cheap at a autozone.
