Mickey Update

Mickey is aging, although gracefully, given the ridiculous amount of mileage I’ve put on her. She’s creeping up on 24,000 miles. The reflective strips I put on are now peeling apart, so I need to get more. The Yamaha logo emblems are blackened from heat. All the black parts are faded. Well, the red parts are faded, too, but it’s a bit less obvious.  Info …

2008 Yamaha C3 (XF50X)

  • 49 cc
  • 4 stroke
  • Fuel injection
  • Liquid cooled
  • Electric starter
  • Kickstarter
  • Red

Owner’s manual – LIT-11626-21-65

Parts replaced:

  • Tires (twice)
  • V-belt
  • Right handlebar switch assembly
  • Right mirror
  • Roller weights
  • Filters
  • Headlamp assembly

The center stand has a persistent issue where over time it gets loose and bounces around when I hit bumps. It needs periodic adjusting.

The trunk lock had to be bored out early on. Locksmiths generally cannot handle scooter trunk locks, and I had dropped my keys inside before it closed. I’ve never replaced this part, though I may in the future. I don’t keep anything worth stealing in the trunk.

As a 49cc machine, the acceleration is woefully slow and going uphill is slow as well. Carrying a passenger is prohibited in bold text all over the manual, with good reason. Heavy loads make it behave even more sluggishly. The owner’s manual says that rider and cargo should not total more than 180 pounds, although the service manual gives a much higher figure, 360 pounds if I recall correctly. If I’ve been grocery shopping and have both the trunk and the big rucksack full of canned goods, I can really feel it.

That said, she doesn’t give up. I rode her up to Suncrest, a ridgetop community that’s pretty high up with some really steep access roads. She chugged up faithfully and steadily without so much as a sputter. Just really slowly. If I could figure out a treat to give her, I would have.

I haven’t done any recent mileage calculations, and I’m preparing the data I’ve logged to upload to fuel.ly but the range tends to be between 88 and 100 mpg. It’s a lot of data; every drop of gas since I’ve had her is logged. There are some entries that were destroyed by leaking milk two weeks ago, which annoys me a lot, but what can you do?

Mickey’s Fuel Economy

So I got my fuel log uploaded into fuel.ly – some odometer readings might have been flubbed because some of these MPG figures are not real. I did flag the missing entries due to the milk leaking onto the pages (or it could have been water – there have been a few incidents) so in theory fuel.ly should have been able to compensate for them. Still, there is such a sheer wall of data that the anomalies ought to mostly average out.

A few items:

  • Since moving to Utah, my mileage is better. It was usually just under 100 in South Florida but has mostly been over 100 in Utah County.
  • Overall average is 105.1 mpg.
  • In almost the entire time I have owned Mickey, I have spent $586.77 on fuel for her. I started tracking the cost after having her a month, so that’s 2 September 2008 to present.
  • After I had her for a year, I met an ol biker who suggested I not crank the throttle all the way. He said I should try it and see if I get better mileage. I did that from 22 July 2009 until receiving the Scooter in Utah in September 2010. I don’t see any difference in mileage.

I have a spreadsheet in use before fuel.ly. It’ll be interesting to stick this data into it and see if the same patterns occur. The fuel.ly back end is supposed to be more sophisticated, so it could help to to make sure some of that sophistication isn’t causing the jigglies appearing here.

I take a lot of ribbing for not owning a car, but the numbers speak for themselves. Living now in a land of icy winters does mean taking the bus during those months; that costs approximately $80 per month. A few times per year I rent a car for long trips, so there’s rental, insurance, and gas for a car for just those days. (And none of the responsibility for maintaining or repairing it.) It could be interesting sometime to add up the totality of my annual transportation costs without a car and compare them to what they would be with a car. It might make a pretty bold case.
