    When I checked my EVAP lines on my 2018 V7 III, I noticed that the breather valve si connect to an electric wire that I assume is a sensor. Will the disconnection of the valve cause a Check Engine Light (CEL)?

    Post a photo of this. Never seen this on even one, on any model, all the way up to 2019s.

    Ok I just double checked and you’re right! My bad. The wire I saw is the lambda probe connected to the opposite side. I really appreciate your interest anyhow. I love this forum already and my Guzzi. Thank you again for the support

    Just removed the evap line. Below some pictures. I removed the breather valve, replaced it with a fitter 1/4 to 3/16 and left the tank line plugged into the canister so the carbon compound will absorb fumes odor. Then I unplugged the intake line from both sides: canister and manifold intake and plugged the hose on both sides with 2 small caps so the hose remains in place but completely disconnected. Ultimately, installed a vacuum cap on the intake manifold with a clamp. A 1/4 vacuum cap works just fine but I preferred a 3/16 so it goes more snug.

    Indeed, I have also been riding since 1968 and I decided I needed a Motorcycle that I could service myself and suitable for commuting. So I purchased a 2019 V7 III Special last month. Now I have never had a Moto Guzzi before and I had to go to Portland Oregon a 430 mile ride home since there are no dealers in Boise Idaho. I was surprised how the idle seemed rough and it some how felt like it lacked some torque below 2800 RPM. I thought perhaps it needed some miles on it and did nothing about it nor had I read any posts here about it. When I came home I put on some more miles and qt 980 miles decided to do the first service and I also removed the tank so I could route some wires under it for a power outlet. In any case I spotted the hose coming from the tank breather and that Canister was annoying me since it was in the way under the engine where I put a jack to raise the rear wheel. So I decided to remove this plastic junk while I had everything apart. SO I went to the Automotive parts store and found rubber vacuum caps and a small sintered metal fuel filter which fits in the rubber hose that comes from the tank. I then removed the canister and the hose from the inlet manifold plugged the inlet with the rubber cap and a hose clamp. And plugged the filter into the air inlet from the tank and finished my service and put everything back together. And surprise the idle was steady and I now have smooth torque from 1500 RPM onward (depending on gear) That is when I started to see if this was unique to my experience and it appears not. When I checked the one way valve that is supposed to only let air into the tank not out it did not work properly and I could blow air in both directions. This part seems to be a cheap part and I would replace it with a metal part with a spring and ball bearing if I wanted to keep the evap crap. Since I live in Idaho it is not needed so good riddance. That is my experience with it...
