What is the fuel capacity for a 1987 Yamaha venture royale?

Greetings... 5 gallons. The Idiot light usually comes on when you have about 1.1 gallons left. Most Venture riders put the fuel petcock on reserve and use the dashboard gas guage and idiot light to determine fillup time. It's NOT a good idea to run it dry - as it's rather difficult to get started if you do...
