I have a 2010 50cc Roketa Bahama. Like with my car, I drive it easy to help maximize gas mileage.
During the middle of summer last year I bought 3.281 gallons of gas for $12.27. I started using that gas when my tank was 1/4 full. At that time, I had 1,736.6 miles on my scooter.
After all that gas was used up and my tank was 1/4 full, I had 2,134.6 miles on my scooter.
Miles after minus miles before for total miles traveled on the gas:
2,134.6 - 1,736.6 = 398.0 Miles
Miles traveled divided by the number of gallons of gas used for miles per gallon:
398.0 / 3.281 = 121.3 Miles per gallon
Price of gas divided by number of gallons for price per gallon of gas:
$12.27 / 3.281 = $3.74 Per gallon
Price per gallon divided by miles per gallon for cost of each mile traveled on my scooter:
$3.74 / 121.3 = about $0.03 Per mile
In my state, beer and soda cans can be redeemed for 5 cents a piece. Every time I went to my friend's house on my scooter, I took any cans I could find. I collected 29 cans while I was using that 3.281 gallons of gas.
Cans times the 5 cents each is worth for total amount earned:
29 x $0.05 = $1.45 Earned
Price I paid for that gas minus the amount earned from collecting cans on my scooter while using the gas:
$12.27 - $1.45 = $10.82
So I basically went 400 miles on $10.82. Scooters are awesome!
Note: While I was using this gas, my carburetor's needle valve stopped making a proper seal. It flooded, even soaked my air filter with gas. More gas was also wasted while I was fixing it.
The numbers could have looked even better if it was not for that problem.
Also, in case you're wondering, "Why 3.281 gallons". I wanted to use up more than just one gallon to help average out the millage. And the gas can I used is a metal one with lots of dents in it, so it holds an odd amount.

Something looks off on your MPG rating.
121MPG, unless you're riding a constant 35MPH for hours on end, I think it's hard to get these values.
For most 50cc's, a 100-105MPG value already is a great MPG!

I write my odometer reading and the amount of gas I buy at each fill up. Octane rating (because sometimes I switch to see if I feel any difference), current odo reading, current price of the gas, the date, and the volume of fuel I've bought. I have a small stack of 3"x5" cards with a hole and a zip-ty keeping them together, kept under the seat, which has to be opened to put in the gas.
I haven't bothered to calculate in a while, I did early on. I did make notes when I made changes in the carb.
When I get my new exhaust on and the EFI kit, I will do the math more reliably.
Now if the weather would cooperate, I could get some riding in. Rain in the forecast for all week, and chilly.

My Tomas 2 cycle got like 110 mpg This 50cc 139qmb gets like  . It's the belt heat that is causing the difference. The belts waste heat. Gears don't. Gears are better. High pressure tires help. Now I don't get but like 60. 47 mm with rich run condition, (cooling). I used to baby the 139qmb, but now I don't. I let it go to the Max. Blows up it blows up. Build a new stronger one and run the "p" out if it. I cruise at 35 all day long. Drag race off the signal lights. |

Also, the odo on many scoots are in KM, not in Miles.
So it might be your 121MPG number has to be divided by 1,6, to go from mi to km; which would turn out to be 75MPG, which is a normal value for 150cc scoots, or 50cc scoots with enlarged (non-lean running) jets.

Or it could also be that the odometer doesn't record accurately. So many possibilities! lol. My odometer shows about 12% more kilometers than I actually go. I verified this through GPS. I think you're probably right though about him reading it in miles, but it's actually kilometers. My 150 gets  mpg (according to fuelly which is going to use my odometer readings), which really is going to mean I'm getting about 75 mpg. That makes his spot on the same as what I'm getting. |

When driven a distance wide open my 50cc routinely gets 105-110 mpg. I thought this wide open driving would hurt the efficiency, but i was wrong. It just doesn't like stop lights/signs. The odometer is in miles and gps verified to be accurate.

I've drove to my friend's house with both my car and scooter and checked the distance with both vehicles. My car read 17.4 miles and my scooter read 17.7. So the scooter only shows an extra 0.3 miles for about every 17.5 miles traveled. I wrote down the number of cans I collected each time I went to my friend's house. 9 entries were made. Let's imagine I went nowhere else but to my friend's house on my scooter and let's use my car's reading for the distance. If it's 17.4 miles one way to my friend's house, which would be 34.8 miles round trip, and I went there 9 times, that means I drove 313.2 miles. Divide that number of miles by the gallons of gas I used (313.2 / 3.281) and that would be  .5 miles per gallon. That's still great gas mileage. I few things I do to help mileage are: I usually cruise between 25-35mph and only do more than that when going downhill. The throttle is rarely open much more than halfway. My tires should be at 36psi but I set them to 40 and check them at least once every 3 weeks. I basically never use the brakes. I ease off the throttle and let the bike roll to a gentle stop without braking. I lean forward when I ride. With my head close to the rearview mirrors, like the position of a rider on a sports bike, my upper body doesn't catch wind like a seal of a boat. |

I can get upto 108MPG riding at WOT, avg between 35 and 50+MPH (depending on wind and hills).
From 35 MPH and up, the variator is maxed out, meaning I'd get the best gear ratio, and the best MPG there!
Going faster than 35MPH, MPG automatically will go down, as there's more wind resistance to overcome at higher speeds.

Mac
Get a life
Forget the cans
Just put some damn gas itn it and go for a ride, forgetting about if you get 108 or 106 MPG.
Damn dude, let it go.

I like the can log. Not sure if its worth the time and effort, but its frugal and amusing at the same time. I hope you can get enough cans to completely subsidize your fuel, and give us a 'miles per can' or mpc rating  |

 Are you sure the scooter is not reading km verses miles. Most 50cc scoots have a 10 inch tire, which claims one is going faster than they are. So 400 km may only be around 250 miles per tank. Attachments:

I'm sure it's recording in miles. I once looked up a destination on Google maps. It said the distance was exactly 10 miles from my house. When I drove there on my scooter, the odometer had gone up 10 miles.
Just so you all know, this is like a little game/hobby to me. I do enjoy the rides and have fun. It's just interesting and amusing to see how cheap I can be with my scooter.
I do this same stuff with my car. I have a 1996 Ford Escort LX (2 door hatchback). EPA MPG: 22 City, 25 Combined, 29 Highway. I once got 37mpg and that was with combined traveling.
Yes, completely subsidizing my fuel cost with the value of the cans I collect would be awesome.

you probably spend more on gas (acceleration) and brake pads, than you'd gain from every can you pick up. Anyway, if it keeps you happy, but in the mean time you may have the appearance of a bum, which found a scooter, and is doing a part time job to get money for crack (or something), lol!
Anyway, cans are easier to spot, than dimes.

.5 miles per gallon. That's still great gas mileage.
