Well we're not alone in this - seems lots of GS riders experience this darn annoying issue.
I just replaced mine last fall after 19 mos of riding daily without a problem...then I had the stealership put in another...and that one just failed a few weeks ago.
If you sputter out of gas on the highway, pull over, lay the bike down to the left, pouring fuel right to left and you'll have about 1.5 gals to get you to the nearest station. Done that game 3 or 4 times now.
The fun thing is in heavy stop-n-go traffic in DC - when I do it, I lay the bike down and then muscle it back up...the looks you get are to die for.
Watch your mileage! I hit 300m and seek the station, because somewhere between 3-325, I'm done.
Smooth throttle and spirited twisties!
