My 1996 Yamaha V-Max gets terrible gas mileage. Other riders I've bumped into tell me that's the way all V-Max's (maybe just from that time period?) are. Others have suggested maybe the ports were modified for colder weather. Any ideas? I'm guessing I can go 50 miles on a full tank.
Is it a triple? I know my 98 Vmax 700 doesn't do all that well, and when I get on it even worse. But it's expected from a triple. However, if you're only running a twin, then perhaps your jets are incorrect, which would make your machine run very inofficiently, and burn a lot more fuel. Other than that, maybe it was bored over more in it's earlier life.
