    Better a tiny bit of moisture than too much vacuum in the tank... !

    I had the swoosh problem. Until I fixed it I always made sure to relieve the pressure often. Can wreck tank and lead to running problems when it builds up.

    So where exactly is this tip valve located? Is it part of the removed evap system?

    Yes.

    All the bits are gone on my 2014 V7 Special. I ran a new vent hose down from the tank and plugged the manifold take-off with a vacuum cap (clamped for security). Everything else in between was removed.

    Planning to do so in the next week or two after the first full service (this Saturday).

    I will do Todd's ECU update, remove the EVAP system and do the SAS removal. Got all the parts, just want the first dealer service done first. Then time for some real fun.

    I just gotta say, I am lovin the heck of of my Silky (2017 Anniversario).

    Do you think you could take some good step by step pictures? It would be extremely useful

    I'll see what I can do. I usually start a project, take a couple of pictures and then get so into the project I forget to take any more pictures. But will do my best.

    For those who are a bit more visually minded here is a CAD image from the service manual showing where to cut and block the hoses.

    To block the vacuum hose I used a $0.68 dowel rod from ACE hardware and a couple of small hose clamps. It's similar to Godfrey's method but using hose clamps rather than glue to secure the plug/dowel.

    Thanks for your guides, Godfrey.

    Dude thanks tequila sunriser!
    So let me get this straight..
    1. Cut #5 and plug with a slug on both ends
    2. Cut both sides of #3 and let them hang

    Second question is about the functions and just want confirmation I have this correct
    1. #3 comes from the gas tank and goes into the carbon filter (cylinder at the bottom of the image)
    2. #5 goes into throttle bodies to be burned off

    If my process understanding is correct all I have to learn is SAS removal!

    1.1 Yes, alternatively you can just remove the hose from the evap can and plug it then cut the hose above the filter. (that's what Todd recommended.) Ultimately they achieve the same result. A 3rd method would be to remove the hose labeled 5 from the throttle body and cover the port with a vacuum cap, and to cut the line labeled 4 above the breather valve (#3). You could then remove the evap can entirely.

    1.2 Yeah, you could let them hang, but I secured them with some zip ties to keep them in place. The ends are completely open though.

    2.1 Correct.

    2.2 Correct, burned off/recycled

    So i just competed it.
    Snip the round ufo thing off, cut the tube from the y connector thing, and plugged it with a metal cylinder thingy-ma-bob, then removed the can.

    So instead of plugging this with the tube, i can just use these plugs and reinforcing rings at the tip valve right?

    I just had this happen to me as I removed the EVAP system and I got replacements from my local dealer.
    Yamaha, part # 90183-050A6.
    They fit perfect and are nice and strong.

    Richard for the above info. I have a 2013 V7 and am still confused as to which line is which. Attached is a photo of the canister, which line is which and can I simply remove these fron the canister and block them off. Anything else to do. Thansks in advance.
