of Fuel Range (main and reserve) - 1979 Kz1300 A1

42.7 miles to empty running at 55 - 65 mpg - from actually riding the bike to empty, up and down La Panza Road.

Calculating it out results in more miles.. but I don't think the tank will fully drain...

82,253 ending miles minus 82,234 starting miles equals 219 miles on the day.

Tank Capacity
@ 30 MPG = 169 miles
@ 28 MPG = 158 miles
@ 35 MPG = 141 miles
@ 35 MPG = 141 miles

At 219 miles ridden, took 4.591 gallons to fill.

Tank size is 5.6 gallons.
5.6 - 4.6 = 1 gallon left
(after I had already ridden 24 miles into Reserve)

1 gallon @ 30 mpg = ~30 miles + 24 already ridden for ~ 50 miles total on Reserve tank.

Two questions:

Do you still have the original fuel tap installed?

In Spain we have 95 or 98 octane gasoline, what type do you use?

No, I'm running the Pingle Petcock.
In the USA, I run 'Plus' which is between Regular and Premium. Not sure the octane.
I just did testing today to calibrate the fuel gauge by draining 1 gallon at a time to know how much fuel is really left in the tank.
Will post that up later, I'm tired.

Reserve Fuel, Pingle petcock.
Slightly less than 1 gallon.. might be some left in the tank.. tried 'sloshing' best as possible on center stand..

Just FYI, another data point.
