I've noticed the past couple of days when I've got my V-Rod out that my gas mileage is terrible. I filled up yesterday, drove home (7.2 miles after resetting the odometer) and it has sucked 1/8th of a tank. What in the world? What would be some of your first suggestions for this? Its due for a "checkup" which I usually do at the start of spring, but I have a feeling this is something really bad.
