301.1 commuting miles on one tank of gas

[Davec719]

Thanks to all the construction and slow speed zones on my daily commute, my "miles per gallon" figure has rocketed to almost 64 mpg.
Filed her up this morning with 301.1 miles on the trip and she took 4.728 gallons. The reserve trip showed 40.0 miles.
Anyone else got over the 300 mile mark on a single tank of gas?

keep in mind that number reads high due to speedo error.

I don't think so. IIRC the odometers are correct regardless of speedo error.

[rg-one]

Interesting... I stand (possibly) corrected!

So how many gallons does the tank actually hold, taking into account the size of the pump?

I usually put 3.7 gallons in with a bar or two showing (~150 miles)

I have gotten 400 kms with the reserve, babying the bike. THat's only 248 miles, so way to go!

damn... im getting like 160 miles outta a tank, i dont let it go to reserve tho, i usually top it off again at 2 bars or lower.. my highest so far is 46 mpg

Pics or it didn't happen! And yes the odometer is very accurate despite the speedometer discrepancy.

Once I can work out how to download from my cell I'll post it (I only took it 'cos I knew some smart arse would request it )

6000 ft. of altitude helps a lot. I averaged 22 mpg in my explorer when I spent a week in Panguich UT (6500 ft). Normal mileage for that vehicle was 16-18

Yeah, I'm sure altitude plays a part but I "normally" average around the 57 mpg mark and this is all commuting. I do baby her anyway but I can only atribute the increase in mpg to the "40 mph go slow zone" on a 6 mile stretch of highway I take each day.

Odo is accurate even if speedo isn't? Someone wanna explain that? If your bike thinks you're going 10% faster than you really are, it would make sense that your odometer would rack up distance 10% quicker.

ok I get it. your tires rotate the same number of times per mile no matter how fast the speedometer translates the rotations. im retarded.

I hate you






j/k I get like 35 tho

I think you get it. A speedo and odometer are both run from a single signal source that counts off distance traveled. On a set of digital gauges like we have on our bikes it is most likely an electronic pulse that represents a unit of distance. The odometer counts each pulse and adds them all up to measure how far you traveled. The speedo uses the distance counted during a period of time and divides distance by time. That is where we get miles/hour or Miles per hour. Yamaha and other manufacturers have decided to add a percentage to the actual speed in a feeble attempt trick us into slowing down but for legal reasons they make sure the odometer is correct. On our bikes the speedo is high by ~10%. If you correct the speedo with a speedo-healer you lower the reported speed by 10% by cutting the number of pulses sent to the gauge by 10%. This fixes the speedo but now the odometer counts 10% fewer pulses resulting in your odometer being low by 10% and making your gas milage appear to be 10% lower in the process. Please forgive my rambling Physics and Math lesson. I hope someone besides myself can follow it.

and the odo will be off with a speedo-healer, right?
