I just traded in my '07 Yamaha RSV for an '07 Goldwing (lev 3). I am new to the site, so I apologize if this has already been discussed. My question...the book says the tank is 6.6 gals...is it possible to put that much gas in when refueling? The reason I ask is that the Yamaha would only allow approx 4.3 gals due to a tube at the top of the tank that trapped air and restricted the capacity. Thank you for any info.
