I had considered that (when I had to go on reserve after only 130 miles)
but then I was using the indicated distances on road signs as well as my
map to back up the odometer and it was about 95% accurate for the rest
of the trip- so it was actual fuel consumtion measured over a set
distance. I think Pat is right, it was the difference between 65 and 75
mph-

Hi Brian,
My crusty, trusty '70 220D Mercedes has a little problem with the
odometer that sometimes causes something inside to slip when it has to
roll over a big number (such as 60,000 from 59,999). It'll do it just
rolling over smaller numbers occasionally. Nearly made me have a heart
attack when the mileage dropped from 34 mpg to 24 mpg! Maybe something
similar is happening? Cheers,

I just completed a 1000 mile ride this weekend on the '74 LAPD and
noticed something really strange with my fuel use- for the first 500
miles or so I believe I was getting 42mpg- then on my way home, it
dropped to around 28mpg- I have not been tracking it too much around
town the last few months, but from my last longer trip I remember it
being around 40mpg (which seems about the same for most of the
loopframes I have owned) So I can't figure out what caused the sudden
drop- because the bike is running exactly the same as it was before as
far as I can tell. I checked the tire pressure and I didn't add anything


to my bike during the trip like luggage or anything (but I doubt it
would have that much of an effect). There was no change in altitude
during the trip and I was driving the same speeds during the whole trip.


Does not seem to be leaking gas anywhere either. WTF???? Any suggestions


appreciated,



Charlie
