Yes, it sits directly below the canister. It has a line on both ends (one going to the three throttle bodies and one to the canister), with an electrical connector on one side. It shuttles open and close to pull stored fuel vapor from the charcoal canister and is controlled by the engine management system. The canister also has another vacuum line from the #3 throttle body that controls the outlet line to the fuel purge valve via an internal vacuum switch. It opens when you start the bike and stays open while running. My thought is if the fuel purge valve is stuck open, the throttle bodies will pull excessive vacuum in the tank, once you shut down, the canister internal valve closes and keeps the tank in vacuum. If you are not keen into blowing through the valve, try running the bike until you build up vacuum, then unplug the line from the canister side of the fuel purge valve and it should relieve the vacuum. The bike must be running as the internal vacuum switch must be open.Your talking about the purge valve that's part of the evap system correct? Has the electrical connection?
