Tank Range
on: July 20, 2020, 08:53:31 PM
Had a ride out to St.Abbs yesterday with Stew1200, what a busy wee fishing port.
On the way back I went into reserve, flashing 0.4.
Managed to fill up in Camelon, thought I was going to run out. Checked my mileage since last fill up and it was 347 miles. Amazing fuel consumption.  :046: :005:

347 miles is pushing it  :005:
No 'range anxiety' with this bike.

I was on the Ohio Turnpike on my 1100 Shadow getting about 40 mpg and expecting a gas station at a service area that turned out to be closed. The next one was something like 60 miles away. Five miles from it I started running out of gas when I remembered the reserve tank and turned the petcock and made it to the next stop. It scarred me. Is it hard on the fuel pumps on our bikes to run the tank so low?

Never had any fuel pump issues running FI bikes low on gas. As long as fuel is going through it cools the pump I guess.
I did have an issue with a manual reserve petcock though. I never used it, and moisture and crud built up in the reserve draw volume of the tank. So when I did finally had to switch it to reserve, all that muck just plugged up the internal filter screen leaving me stranded beside the road.
Since then I try to leave it on reserve unless Iím riding in an unfamiliar area.
(Not an issue with CB5X, no manual petcock so the fuel pump draws from the lowest point in the tank)

How do you do that?  The most I ever got on a tank was about 245 miles (if I remember correctly).  On that tank the Trip A was flashing 0.9!! when I rolled into the gas station.  I usually assume I can go 240 miles on a tank but start looking for fuel at about 180-200 miles.  Of course you can see my Fuelly report below, 54 mpg lifetime.  A lot of high speed miles!

As AJ500 says, it's probably the high speed killing your economy. I normally ride to the speed limit here, but don't ride like a granny either.  :008:
Here's a link to my Fuelly stats, but I no longer record them.

Yeah once you start to go over 60mph for long periods the fuel economy will begin to dive. I used to regularly get 250 miles before the low fuel light came on, that was pure commuting (only 12 miles a day). I dare say I could have easily got over 300 miles on longer rides.

Yeah, there are some places I ride where I keep the speed below 60 mph, but not many.  Most of the time I am riding at 70 mph, or more!

Come to think of it, the best mpg I ever recorded was in the twisties of the Ozark mountains in Arkansas.  I rode for three days going up and down mountains on very twisty roads.  I was cornering at about 35 mph and would accelerate to maybe 60 mph between curves.  I rode almost all day in fourth and fifth gears only accelerating to 70 mph occasionally.  Each day, I got really good mileage but one day I got 71.3 mpg for the day!  I was shocked and have scratched my head over that one ever since.  How could I ride repeatedly from 500 feet elevation up and over 2500 feet elevation many times each day and get such great mileage; it was the speed!

Here in Alberta, if you ask somebody how far it is to someplace, you will get a time reference, not distance. How far is it from Edmonton to Calgary ó about 3 hours. Lifetime, Iím averaging 3.5 litres/100 km or 79.5 miles/Imperial Gallon. I work on the presumption that I can travel a bit more than 4 hours before going dry. I prefer not to chance it so Iím usually filling up at 3 or 3 1/2 hours.
Iíll think of something later
