V7 cannister removel

[drlapo]

I've removed the charcoal canister from my 13 v7.
I'm looking for the "valve" to also remove. is it the blue and orange disc located in the line under the left side cover?

Guzzi Steve, who is a Guzzi mechanic posted this in another thread.  So, it appears that you have found it.

Make sure it has the upgraded tank vent on it. NOT grey, it is blue & orange and right behind the left throttle body. This took care of the tank problems.

[drlapo]

that was easy, thanks

If you remove the valve, water vapor will be able to freely diffuse from the atmosphere into the fuel tank.  That's fine if that's what you want.  The purpose of the valve is to prevent this from happening, while still allowing the pressure in the tank to equalize with the outside air pressure.  There's a reason why Moto Guzzi puts these parts on their bikes.  Second guess their engineers at your own peril.

How did you plug the line from the cannister to the throttle body?

[drlapo]

the line, that the blue and orange valve was in, went from the fuel tank to the canister behind the sump.  i assume the other line from the canister goes to the intake to recycle the vapors that came from the tank.  so if I let the large tube, the one with the valve, just dump  below the bike any vapors in the tank will vent out the tube and air will enter the tank via tube as fuel is used.  the smaller tube is plugged to prevent air from going into the intake. is this correct?

Yes, I was wondering how you plugged the line to the intake?

But, why?  Do you have a compulsion to contribute to air pollution?

[drlapo]

I just put a plastic plug in the smaller line.  I may cap  it at the "source" but I don't know where it ends. I'll look for a schematic

I've inspected the blue/orange valve and can't determine how it could keep water vapor out of the tank.  it has no desiccant in it or a chiller to condense the moisture.

I won't respond to the air pollution remark

The "source" should be the bottom of the intake to the throttle body. 

[drlapo]

I checked out the schematic at Harpers, removed the "return" hose and capped the port on the intake manifold with a vacuum port cap; all done
I'm sure the bike will run much better and cooler now that the air can freely circulate behind the sump (now just wait for the comments on that theory)

I'm not convinced about the "run cooler" theory but taking the can off will certainly make it easier to remove the rear oil drain bolt.

The valve prevents free diffusion of air, which contains water vapor in humid weather, into the tank, and prevents free diffusion of fuel vapor out of the tank, too.  It still allows air to enter and leave the tank to equalize the pressure.  The opening of the valve under a pressure differential is what is sometimes heard as a groan or whine.  Another function of the valve is to prevent fuel from running out of the tank and onto the hot engine and exhaust pipes if the bike goes down (I'm sure you don't have to worry about that because you've never dropped a bike).

We understand -- it's nothing to be proud of, and there is no good response.   ;)

is that last comment really needed?

Sorry, my snarkiness got the best of me.  But, more seriously, this is a safety feature.

In this ever increasingly over regulated, government stranglehold country, no one reasonable is going to give a crap about Moto SMOG restrictions. Considering all motorcycles combined make up less than a few percent of transportation miles in the US, it doesn't add up to enough to make a stink about. Uncap 'em and let 'em breath. Ahhh, now doesn't that feel good?

I'd have hard time naming a country with less regulation than the US.  Care to try?

Afghanistan, Nigeria, Syria, Honduras
All great places with very little government oversight or regulation. Some might say 4 Libertarian paradises right there.

"let 'em breathe" ; maybe I'll name my V7 "commando"

Much like the auto door lock on my Nissan Rogue when I get to 15mph.  really, do I need that engineered into my life!

There's probably an Easter egg to disable that if you don't want it.

Less regulation, how about no regulation. Both India and China, have zero environmental regs. Recently China said they'd consider starting some regs in the year 2030. Seriously, I'm not making that up.
