My bike gets down to 1gal. of fuel and won't run anymore! Checked vents and changed filter! Runs fine after adding more fuel. Bike has very few miles also.

how many miles are you into your fuel reserve when this happens? How many gallons does it take to fill it back up after it dies?

I'm not sure exactly but I have drained the tank twice after having the problem and both times there was a little over a gallon left in the tank.
