Never thought about this until the first time I filled up. Does the tank still take 5 1/2 gallons full? Reason I ask is my low fuel light comes on at about 140 miles but when I fill up it only takes about 3.6 gallons. Right now I figure I'm getting about 38.5 mpg. It's a CSC conversion of my vintage. Indian's owner's manual states the bike is supposed to be filled up resting on the side stand.
