    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.

    This explains it all. Cut it free block or delete small hose. View attachment.

    I don't understand how the canister work but I am starting to think if we block inlet port on intake manifold completely, remove hose from canister to manifold or cut it short and remove check valve then the reconnect the hose. Will the fuel tank still breathable? I think if I leave the remain system without check valve will help slowing the fuel leak when crash.

    For those who did this mod, what do you guys use to cap the hoses once they have been snipped?

    I want a clean look and am thinking a rubber/plastic end cap with oetiker clamps?

    I left the hose attached to the intake but plugged it with clevis pin I bought at Home Depot. I bought three diameters and returned the two that wouldn't fit.

    I'm thinking of using Tequila's third method: Remove hose 5 and cut above the breather valve #3 on hose 4. If possible, I'd like to remove hose 5, 4, evap can for a clean removal and I see less hoses in the maze and if the next user wants to put it back on, it is an option.

    Do you by any chance remember the diameter? Attached to the intake, I'm assuming hose 5? Thanks for your input.

    I finished the job today. Remove all system completely. Reuse original hose and add smaller diameter hose at the end.
    On intake, I use 6mm silicone cap to block air inlet.
    Edited: I don't cut any hose but file the bent edge of the clamp and use pliers to remove the clamp. So all of them was removed without any damage(except hose clamps).

    Did you plug the remaining vent hose? We’ve all left it open to air.

    Me? No, I left it open like in my pic 3. I just extend it with smaller diameter hose. Thank you for asking.

    Did I do something wrong? After doing this mod, I was menuevering my tank a bit and gas started to come out of the snipped hose that use to have the filter on it. Will this happen any time I fill my tank up all the way?

    Yes it will... this is why I recommend gutting the tip valve and leave it connected to the evap can if you leave that in place. If you eliminate it, don't fill your tank all the way. I usually leave mine ~1/2" below the filler neck.

    Hey, Todd seems to recommend a slightly different approach. Leaving the canister in place will prevent gas leaking on a full tank? Not sure how:) Is there a link of his procedure?!
    Thanks for your time friends.

    I removed mine last summer and always fill to the top of the tank.. Have never had any issue with gas leaking.
