wanna bet! I found out the hard way, if you don't switch to your reserve every couple of fill ups you will be in for a big surprise. on our way back from Don's MD, we were almost home so I let the tank run down to reserve. When I switch over, witch was the fist time since sometime last year I got nothing but water. Lucky thing we were only a mile from a gas station. When we got home I drained off at least a 1/2 gallon of pure water. I don't know where I got it from. Maybe a bad load from a station on the road, maybe it was there all winter. All I know is, my tank will be on reserve all the time from now on. I still can't believe the bike ran great all the way to Ohio and back with all that water in there. Never once did it hickup.
