LOUSY GAS MILEAGE ON 150cc

25 MPG??? You've got a serious problem. A Harley will do better than that. As will my Subaru.

Are the brakes stuck? Do the wheels spin freely? Do you weigh 500 lbs.? Are you leaking gas on the ground? I can't figure out how the engine could go through that much gas without fouling the spark plug in the process. How does it run?

How big is the tank, and how far can you go on it?

My tank holds 5.4 liters. How's that in gallons? It rides really well, though maybe a bit rough idling... which is normal for its size, right?
I'm serious, I do not get anywhere near what the seller told me I'd get: 75-85 mpg, not even close.
I guess the best way to check is to fill it up, note the odometer, then ride it til it's empty and note the odometer, right? Has to be a better way than to have to run out of gas to check it.
Any other ideas?

Is the choke working?

I would almost bet that your auto-choke is defective. Did you look at your plug? Is it black?

It's either that...major gas leak...or your valves are way out of spec.
