Gas mileage very low

My 2003 VN750 is getting about 38 miles a gallon. What does everyone else get? Is mine extraordinary low? Bike might be running a little too rich.

Really no way to tell without knowing any mods that have been done to the carbs and/or exhaust, the weight the bike is carrying, your driving habits, etc. etc. I've read on here people getting anything from the upper 30s to into the 50s. Just depends.

Do you have any modifications to your bike? I average between 47 and 54 mpg depending on how I get on it. On long rides it is mid fifties and running around town with a heavy throttle it is down lower. Check your plugs and see what color they are when you pull them. That can tell you if you are running lean or rich. Let us know what you find and we should be able to suggest ways to correct your situation.

There are plenty of people in the Jersey area if you have an interest in group rides or may need some help.

and always remember, "Ride until you rot!"
**Really not sure if the Big "C" is back right now
but having to face the fact that this is a lifetime routine
going forward. Five operations done and it still continues.

also it depends on how you are reading your miles too.

real miles or what the odometer tells you? There is a difference.

Great replies.. thanks! I'll try to take a look at the plugs this weekend. No mods that I know of (bought it last year used).
The only way I can measure is with the odometer reading. Even if it is off a little, I don't believe it would affect the mpg that much. The best I've seen with mostly highway is about 43 or so. I can do about 115 miles per tank (based on odometer).

A 10% off odometer reading is not an out of this world possibility. 10% puts you from 44 down to 39.6

Surprised you guys haven't told him what oil you use, if you have a windscreen and how much air you put in your tires....

I averaged about 38 mpg in my Vulcan, and it was stock and had less than 5,000 miles on it when I did the math. Got about 43 on the highway too...

If your plugs look good I'd not worry about your mpg figures too much. There are ways to coax the bike to get better gas mileage if that's important to you.......
