I’m putting in my termi system on my 2018 v4 and was wondering if I could leave the evap canister out looks like there a wire running into one of the rubber tubes
It's common to remove it and put a bolt into the end of the tubes from the air box.
I don't know if you'll get an error code? Or if the upmap clears the error (like it does for the lambda)
There's no error codes for removing the canister. The dealer that did it is closed down now so I can outright say it, but they removed my evap canister at my 600 mile point because I was getting some stalling/chugging when the bike was hot. Never had the issue ever again.
