2003 EFI RK. On a recent ride, I ran out of gas, yes I know you should not do this for various reasons. Doing about 85 mph, it just quit, game over. While talking to the guys I was riding with, just for grins, I wanted to see if she'd fire up.. she did. We rode about 4 miles to the gas station. I like to know how things work, so this is what I have figured out so far. Going this rate of speed, there was a lot of vibration in the tank, which caused the pump to start picking up air, this caused the shut down. When I fired her back up, because I kept my speed and rpm's down, I was able to use what was left in the tank.. sound about right?? It took 4.9 at the pump, 5 gal tank.

Sounds plausible to me.

And very fortunate.

You have a divided tank. Most fuel transfers from side to side at the rear of the tank. Below a certain point, than it relays on the crossover tube.

There's a cross over tube in the front of the tank, underneath. If you use more fuel faster than tube (1/4" ID) can transfer, bike shuts off.

The time it takes to pull over, as well as if you placed it on the kickstand and looked around a bit, fuel from right transfers to left side. Pickup is on left side.

When you parked with the bike on the kickstand fuel from the right side of the tank drained over to the left side where the pump is located giving you the extra miles of ride. That holds true for carbed H-Ds too. There's always some extra fuel left in the tanks.

Idiot light came on just as we were passing the first stop for fuel, 38 miles to go... bike gets 32 going that fast (didn't know that). Light went on, trip was no where near my magic 160. Died at 157 on the trip.

Thanks for the replies, I'm glad I did think of giving her a rest on the jiffy and trying it.. in the end it worked out. But damn, no sputter no nothing, just dies.
