Did You Know?
Generally it takes a very warm day and a gas tank half full or less. When you park your bike you'll hear a whistling sound that can continue for many minutes. It's just the tank vent. The whistle can be stopped by opening the gas cap for a moment. Occasionally (on a really hot day) even opening the cap doesn't work and the whistle will continue as soon as its closed again. Heat from your engine and the atmosphere have simply warmed the air in the tank enough so it has to escape and it does that through the keyhole. If anyone asks about it, just tell them your Vulcan is "especially happy today." If you hate the whistle, check this fixit page for the fix.
