Charcoal Canister Removal - Detailed with Pictures

    I removed my charcoal canister and I can tell you that the results were outstanding. My idle is normalized and my running is significantly improved. Most importantly, my fuel tank no longer pressurizes when it is in the sunlight.

    ***Words to the wise - I provide this for your information to use at your own discretion, and you alone are responsible for anything you decide to do to your own motorcycle. I STRONGLY suggest that you have a large table/working surface in order to lay out each part and it's associated nuts and bolts in a logical order which you can understand in order to reassemble it when you are done removing the canister. If you are foolish enough to simply just put the nuts and bolts all willy-nilly in a pile, please don't blame me if you cannot get it back together. Also, if you are not confident to decide how tight to tighten nuts and bolts based upon what they are holding, then DON'T DO THIS as you will probably crack fairing parts. Still confident you can do this? Fair enough... Good, let's begin. :D

    ***Note: As you will be removing the tank during this adventure, the less fuel you have in the tank for this procedure, the better. I would not do this on a full 8.5 gallon fuel tank! ;)

    Thanks for that information!

    So glad we don't have that fitted to our Euro Stelvio's! :shock:

    Great job detailing the the fairing and and tank removal, I might need it for future reference. However, I have accomplished the same thing (removing the canister) with just the speedometer panel removed and left the redundant air hose under the tank. I will deal with this hose when some other job requires tank removal.

    Forgot to ask - what are your impressions of the bike/engine after this mod? Did you synchronize the TBs/cylinders after?

    Thank you. I hope people can use this.

    Overall running of bike is markedly much improved. :D Yes, I did both a TB balancing and a TPS reset. I have the Centurion software and cable, and a Carbmate and a MotionPro Mercury Balancer.

    Yes, I had the same observation and that was even without the TB synchro, just balanced the idle without TPS reset.

    That's great Lumas. I was shooting in the dark when I did mine. I guess I shortened the vacuum line to within six inches of the tee and plugged it. Would there be any point in me fishing it out and reconnecting across as you have done? I am travelling and on the road but I am equipped to do it. Even brought the pieces of hose I took out. Also, I didn't run the main back to the front but removed all that excess and ran it directly down by the center stand. But, one of the questions I have been posing here is what exactly that check valve does. Mine is still in place and I was wondering if it was safe to gun it. You say it's a tipover valve. So, with it removed will the fuel come out?

    An excellent informative post. Have you considered publishing a workshop manual for the Stelvio? This is better than a Clymer or Haynes manual.
    Thanks for taking the time to do this.

    Outstanding DIY write-up. :D Any chance of publishing that to a pdf document? I'd sincerely appreciate getting a copy if you do.

    Thank you for your kind words. It was a very large project but nevertheless, a labor of love. I hope that it is helpful to my fellow Guzzisti.

    At your request, I have created a PDF but it is 14.4MB in size and I don't know how to get it to people for free. I will be sending an email to Todd to see if GuzziTech can host the file somehow. I'll post as soon as I hear back.

    Thanks again

    - Scott

    Thanks.

    Very nicely done! Great Photos. I wonder if dealers outside of California will remove it for you?

    Worked like a charm! A huge "Thank You" for doing this. I'm not a Stelvio owner - yet, but the Stelvio is at the top of a very short list of bikes that I'm evaluating for my next ride (I'm on an '07 Yamaha FJR1300 now). DIY guides like yours and the Valve Adjustment Procedure by leafman60 are absolutely crucial to my decision-making process and - I think, will help drive Stelvio ownership by taking off the table the biggest concern that many potential buyers have about Moto Guzzi on the whole: lack a of credible dealer network in comparison to many other brands. Having a factory service manual is great, but it's these DIY guides produced by actual owners that really build confidence.

    Thanks again!

    Did you read what I wrote in the first paragraph?

    "My idle is normalized and my running is significantly improved. Most importantly, my fuel tank no longer pressurizes when it is in the sunlight."

    This IS NOT a performance issue. This is a rideability issue. When the Evaporative Emissions stuff works correctly, it is believed by the engineers that it does not affect running. However, in the real world, often times, these systems are made of the cheapest components and can cause problems with idling and throttle response from idle, as well as built up pressure within the fuel tank.

    Personally, my motorcycle is much better off without it, however, this is a personal choice and by no means do I wish to be confused as saying that everyone should do this to their bike. For me, it was without a doubt, an excellent decision.
