250cc mopeds

1. Maximum speed was 40 km/h (25 mph). The rear wheel was driven directly by rods from the pistons in a manner similar to the drive wheels of steam locomotives. Only a few hundred such bikes were built. and the high price and technical difficulties made the venture a financial failure for both Wolfm

2. You may need to go back to the idle speed screw to lower the idle speed if it s now too fast. So the basic procedure is to set the fuel/air mixture to give you the fastest idle. then use the idle speed adjustment to set the speed to the lowest rpm that gives you smooth running.

3. What MPG Does a Scooter Get?

   This depends mostly on the engine size. The smallest engines are typically 49cc and they can give up to 90 mpg, depending on what type of riding you do and how much you weigh. Obviously if you weight 300lbs and do mostly short “stop and go” trips you’ll get a lower mileage than if you weight 100lbs and travel mostly on long trips at modest speeds. At the extreme, we’ve seen figures of 110-120 mpg for 50c scooters when the rider was trying their best to drive as economically as possible.

   150cc scooters aren’t quite as frugal, but we’ve seen reports of up to 85mpg. With the larger engine sizes (300cc) you should still get around 70 mpg from a scooter traveling at legal highway speeds. That’s about the same as a Toyota Prius Hybrid, but the scooter will be a lot more fun!

   Scooter Wheel & Tire Size

   Motor Scooter wheel size varies from a minimum of about 10″ to a maximum of around 16″. Most are either 12″ or 13″. This is the size of the metal wheel itself and doesn’t include the tire. The measurements is the diameter of the wheel rims The tire may add 5″ or 6″ to the diameter. My scooter has 13″ wheels (rims), but the tire measures about 19″ across in total.

   So what are the advantages and disadvantages of different sized wheels?

   Well, the smaller the wheel the more maneuverable the scooter can be. The smaller wheel has less of a gyroscopic effect making it somewhat easier to turn (though this also depends a lot on steering geometry). So in general, scooters are more maneuverable than motorcycles (which have larger wheels). The converse of this is that larger wheels may give better stability at speed.

   The downside of smaller wheels is that they don’t roll over obstructions in the road as well. Just think of a pothole in the road. If it’s a large hole and a small wheel, the wheel could fall into it! Even if it’s a raised obstruction like a tree branch or a curb, a larger wheel will roll over it with less effort than a small wheel. That’s one reason why off-road trucks often have monster wheels. When you’re driving over rocks a big wheel makes life easier. Similarly, if you’re riding over roads filled with potholes (for example New York City!), you’ll value larger wheels.

   While a few scooters have 16″ wheels (e.g. MC_X1507) and a few have 10″ wheels (e.g. MC-U1504), most scooters have a 12″ or 13″ wheel which is a reasonable compromise between maneuverability and stability.
