When fueling up at a station with 1 hose pumps, it takes (im told) 6 gallons of fuel to start pumping premium if the last guy used regular....hence you are wasting $$$ if you hit the premium button with a 1 hose.
I try and look for a 3 hose pump, hence I get what I pay for. Riding in SoCal with the mountains and steep grades you will know immediately if you got the wrong grade and spark knock can override your radio (loud)......
1)If that was the case, I think there would be a lot of lawsuits for selling the incorrect product.
typical hose size is 3/4" I.D. x 10 feet. 1 gross measured gal to fills 10.93 feet of hose. so you are gtting almost 1 gallon of whatever was put in by last customer.
Good question though. If I'm not mistaken, on the single hose pumps, the shut-off valves are located in the pump itself, which means there really isn't any residual fuel left in the hose. My opinion anyway.
Possibly the pump shut switch off is there but the hose remains fill of almost one gallon. If you dont have pinging I would not waste money on booster, I can get by with unlead as long as I dont hot rod the bike.

If I did my math correctly--
If the fuel hose has a 1 inch inside diameter and the hose length is 10 feet--
I calculated 42.24 ounces of low grade will be dispenced from the hose before
premium fuel is delivered to your tank.--Can anyone verify this using those dimentions?
Back when gas hit the $4 mark, I switched to regular gas trying to save a few cents and my FLH did not notice the difference. I still use regular gas with no drop in performance & fuel milage.
