Why is the fuel mileage not better???

[alaskanflyboy]

Could the fuel mileage be directly effected by the speedo issue?

I mean recorded mileage not actual of course.

The speedo issue is not an odometer issue, strangely. From many test runs, I've found the trip odometer on the bike to match within a tenth mile of the trip odometers on four different vehicles on long stretches.
