My daily work commute includes crossing a small, steep mountain. I've not yet had my Wee ('07) a year, but I've ridden it nearly daily, and I began trying to find the safe upper limit of fuel range. I always fill-up with the bike on an essentially level surface and on side stand, filling to the bottom of the inner lip of the tank.
On this mountain I frequently (nearly daily) lose a fuel bar when riding down the mountain. The bar usually reappears when I get onto less sloping ground.
Over the past couple months I've noticed that twice my bike has "stumbled" (lacked normal power) and I believe it's because I'm going about 280 miles between fill-ups, and that the small amount of remaining fuel is being momentarily moved away from the fuel pick-up in the tank in certain curvy-road conditions.
I faithfully track my fuel mileage (via gages) and I can count on at least 55 mpg (60.x mpg is my all-time high). Considering this, 5.8 gallons should get me to about 320 miles in worst conditions, but I don't like the "stumbling" feeling, and fuel is probably momentarily not surrounding the electric fuel pump in the tank, depriving the pump of the lost cooling from the fuel. Plus there's the somewhat small threat of having to push...
I've decided to stop my quest to get to 300 indicated miles on a tank and just fill-up, with about 5 US gallons, at about 270 gage miles - theoretically leaving nearly a gallon of gas in the tank.
Oh yeah, my fourth fuel bar goes out (fuel pump icon blinking) at about 240 miles. The last (fifth) bar starts blinking at about 260 miles, leaving, I suppose, about 1.0 gallon (55 miles) in the tank.
