Evaporator Canister lines

[docsouce]

I bought my 2002 R1100S in mid November. When I picked it up I noticed the evaporator canister was missing. I asked the dealer about this and he said it was taken off and not really needed. Well I asked him for it and he gave me all the parts he said I needed to remount it. No problem so far... Well today I started to put the thing back on(I picked up one of those relocation mounts) i looked through the Clymers book and really couldn't find how to set the lines up.
I found the rubber hose and connector coming from the fuel tank. I believe this line goes to the center of the canister. Next what I also found on close inspection is a T joining 2 rubber hoses that come from the bottom front of each throttle body. Now this T is open. I didn't have time to start the bike to check it because I had to go to work, but it seems to me that it has to be leaking (or sucking) vacum air. Anyway, is this "t'' where I connect the line from the purge valve on the evaporator system? I also need to know if the purge valve has a direction of flow. Can it be mounted backwards? There is an electrical plug on the bike it that shows momentary power when the ignition is turned on. The plug fits into the purge valve so I suspect that is where it goes. (I know it seems obvious but..)
Sorry if I sound lost here, I just want to get it back together right and can't find any info on it.

Thanks for any help

welcome to the board fellow Mass "S" rider,

just out of curiosity,

why are you putting it back on?

I checked out that article.. I'm picking up a slight smell of "old oil" when I stop. My thought is that it might be coming from the lines that were left open when this thing was removed. If this canister is of no use then I'll leave it off and set the lines up as the article sent suggests. I'll see if that eliminates that odor and if not look elsewhere.. One way or the other that open "T" has to be addressed.

Like Bubba, I must ask, why bother? Its contribution to protectring the atmosphere is negligble to nil (IMO), as long as you don't overfill the tank. At the same time, if you do overfill the tank it has the potential to fill the throttle bodies with nasty charcoal muddied fuel.

I just went through a similar situation with my 1995 R1100R. The carbon cannister went bad and was preventing the gas tank from "venting". Lack of venting caused a "vacuum" in fuel tankwhich prevented float from working which impacted the "fuel warning light".
Professional BMW mechanic simply removed cannister saying "only in California" would this be improper.
When this venting problem was going on the fuel tank began to "leak" through overfolw tube. I later learned the two problems were not related. Overflow was caused by bad tubing & connectors inside fuel tank.
The smell you are noticing may not be related to the tube leading to cannister from fuel tank. I have noticed no smell in my closed garage since cannister was removed.

As other members and BMW mechanic have stated the cannister seems to cause more problems than any beneficial impact it may have on environment.

address that by removing the lines leading from the "T" to the throttle bodies' vacuum ports. cap the ports or use a bit of that line and run it between the two ports. some say this helps balance the tbs some, but i've never noticed a difference. i just have little plugs on mine. leaving that "T" open to the atmosphere isn't helping any and could, potentially, if oil is somehow getting into your airbox through the crankcase breather and ending up on your intake tubes, be leading to that "oil smell" you mention.

I noticed 1 of the lines was crimped 90 degrees,so it wasn't operating properly anyway.Glad to see it's gone and no problems since,even with a full tank and an amazing near drop at a stop and recovery on the right side-no leaks or smells.:thumb

The cannister has been added to my fossil parts area, the vacuum ports have been properly plugged and the bike is back together again. Now if we can get one more of those "unusually mild" days I can take it out for a spin. If nothing else, finding and plugging that vaccum leak made this all worth while.

Thanks for the help/advise..
