I would tend to agree but my bike is brand new.Looks to be a brass hose union (connector) inserted where somebody previously cut the hose, hence the reason for the two Oetiker clamps on either side of it.

The factory will often use those for easier assembly line installation and/or service items afterwards. I’ve seen them often on the newer Guzzis.I would tend to agree but my bike is brand new.
Yes, but not “reburn” - it simply controls the intake vacuum so that it doesn’t constantly pull through the canister. Such an overly complex “solution.” Back in the day the gas cap simply vented to the atmosphere. Now the world is collapsing because of it. You can plug the line below too, just don’t cap the Bosch valve.does the ECU controlled Bosch valve open so the intake can then draw the fumes into the intake
Thanks Todd, does the ECU learn at all from such changes as this?Yes, but not “reburn” - it simply controls the intake vacuum so that it doesn’t constantly pull through the canister.

Hi there.Intend to follow your way as much preferably system to appear stock since bike still under guarantee. Forgive my ignorance but for being on the safe side that i will do it on right way would you please clarify to me whether diameter 5/16” of the metal slug is the inner or the outer one?If the outer what should be the inner one?My 2021 850 Special was experiencing the typical “cutout” issue we have all historically described. My Moto Guzzi dealer mechanic actually called last week and without saying the exact words, encouraged me to pursue the EVAP mod which he said came from their discussion with Italy. Finally had time to deal with mine today. I prefer to do mechanic’ing so things don’t appear like a hack job. So, for my mod, I drilled out the check valve then reinstalled. For the vacuum hose, I made a 5/16” diameter 3/8” long metal slug for a plug. Inserted the slug in the hose 1 inch above the Bosch vent valve, then reconnected that hose to vent valve and reinstalled the factory clamps. All this to say, my system "appears" stock, but functions per the modification. Lastly, as expected, it cured the engine “cutout” issue.
