kwn306 said:I had the same issue with the paint bubbling, Guzzi finally sent the piece after making a fuss about it. Also they said "we" only replace this once.
That said, I found a couple of issues that caused the problem:
1. The tip over valve (it sounds like you have this sorted out)
2. The hose coming from the overflow (hole under the cap on the left side of the bike) was more of a vacuum hose consistancy of hose and the fuel had gotten to it and melted the hose and caused it to kink. I replaced the hose from the tip over valve and the fuel over flow with 3/16" fuel line and this has solved the problem. I also removed the charcoal canister and all associated plumbing, bike runs a whole lot better without it. BTW, there is a one way valve (check valve) located between the TB's, mine was stuck closed, this is another reason the tip over valve didn't work properly.
My Aprilia Caponord had the same type of check valve and it was standard operating procedure to remove the valve and install a barbed fitting in its place so the fuel tank would not pressurize.
Removing all this plumbing ... charcoal canister .... wouldn't it affect the ECU mapping?
In your case ..... for the better!
The one way check valve that you are talking about would it be the lines going to the TB for the Vacumeters?
