I have a 2005 1800 with 7500km . In neutral , on the main stand , turn the ignition to on . When I do this I hear a gurgle or surge of fuel I think ? Sounds like it's coming from fuel tank anyway . It makes this sound for abut 3 seconds . Almost sounds like the fuel system is pressurizing ? Bike starts and runs normal .Never noticed this before , Do I have a pending problem ?
