Guys, did this and removed the hoses, all looks well - when routing the existing fuel evap exit line through the existing cutout in the skid plate, it is tight, tight enough to squeeze/compress the line against other hoses which I feel triggered an error code on mine until I repositioned the exit line. So watch that line does not get too compressed.

Anyone have the throttle not return to 0 after doing this mod? The reason I ask is because I'm on another thread talking about the bike rpm's not dropping off after releasing the throttle. I looked at the evaporator schematic and the return line dumps into the intake manifold which might be causing my issue. Let me know if I'm crazy or not.

In the interest of keeping all information centralized.. The same size ID fuel tubing as the one coming from the tank vent port (filler neck) is 5/16" (7.9mm) ID fuel injection hose. I used just shy of 4 feet in length to completely replace the tank vent from the filler cap to the underside of the motor. That way I never had to fluff with any of the clamped on hoses on the canister keeping it complete.
Since doing the EVAP deletion, my bike is no longer creating a vacuum in the tank, making the gas cap easy to remove when fuelling the bike. Also noted, the bike seems to accelerate smoother and is quicker to start.

I also plugged the connections to the throttle bodies
But, I left the drain hose down to the belly pan. It would be dangerous to remove the drain hose altogether and have gas overflow drip down over a hot engine... it doesn't take that much for a full tank to overflow a bit as new gas in the tank warms up and expands.

EDIT: Nevermind, I believe I found the answer; it's a 5/16" gas line. The vacuum caps are 1/8", as stated above.
How do I ask for the longer hose to go from the gas tank overflow all the way to the bottom of the skid plate? What are the OD and ID?

So my 2016 has an electronic breather valve in the EVAP system (# 24 in this parts diagram: https://www.bike-parts-ducati.com/t...d-2016-Hyperstrada-939-Hyperstrada-939-40.png).
Does anyone know if removing it will cause the ECU to throw a code? What have people been doing with the pigtail that connects to the valve on the wiring harness?
Thanks!
